2026 China Semiconductor Materials Industry (Silicon Wafers + Photoresist + Electronic Chemicals + Targets + CMP + Photomasks): Market Size and Competitive Landscape Deep Research Report

Abstract　Key Findings and Core Data

Semiconductors are called the "oil" of modern industry, yet the true bottleneck rarely sits with the chips themselves — it lies in the ultra-pure materials that make chip fabrication possible. Silicon wafers, photoresists, electronic chemicals, sputtering targets, CMP polishing materials, photomasks, and packaging substrates: each of these sub-sectors has its own technological barriers, and each is a battlefield where Chinese industry is pushing hard for domestic substitution.

China's semiconductor materials market reached approximately RMB 174 billion (USD 24 billion) in 2025, ranking first globally — yet domestic production still covers only 30–35% of total demand. The gap between "world's largest buyer" and "globally competitive supplier" is the central tension of this report.

Report Coverage: Silicon wafers (12-inch and 8-inch, including epitaxial wafers), photoresists (g-line/i-line/KrF/ArF dry/ArFi immersion/EUV), wet electronic chemicals (ultrapure acids/bases, CMP cleaning agents, electroplating solutions), electronic specialty gases (etch gases, ALD precursors, specialty blends), CMP polishing materials (slurries + pads), sputtering targets (metal/alloy/compound), photomasks (semiconductor-grade), and packaging substrates (traditional BGA / advanced CoWoS).

Key data points: National Big Fund III (RMB 344 billion, 70% toward equipment and materials); SMIC + YMTC + CXMT combined 12-inch monthly demand approaching 700,000 wafers; Hermes Microvision acquired by ASML; JSR privatized under Japanese government support; China's KrF photoresist domestic share exceeding 40% (Photech New Materials); Jiangfeng Electronics 3nm target qualification; Anji Microelectronics CMP slurry global share ~10%.

Chapter 1　Definitions, Classification, and the Full Semiconductor Materials Value Chain

Silicon Wafers: The Journey from Polycrystalline Ingot to Single-Crystal Wafer

Silicon wafer manufacturing is not simply "melting and re-solidifying silicon" — it is a chain-based precision manufacturing process involving more than twenty process steps.

At the raw materials level, high-purity polysilicon (purity 9N to 11N) is purified from industrial silicon via the Siemens or fluidized bed (FBR) process. Solar-grade polysilicon (6–7N) and semiconductor-grade (electronic grade, 9–11N) are produced from the same feedstock but at radically different purity requirements. This gap explains why solar polysilicon is already fully localized in China (Tongwei, GCL, Daqo supply over 70% of global volume) while semiconductor-grade polysilicon remains dominated by Wacker Chemie, Hemlock Semiconductor, and a handful of others.

The Czochralski (CZ) single-crystal pulling process is the core step: polysilicon is melted in a quartz crucible (~1414°C), a seed crystal is slowly pulled upward, and silicon crystallizes at the solid-liquid interface into a perfect single-crystal ingot (boule). A standard 300mm ingot is approximately 2 meters long and weighs over 200 kg, requiring 48–72 hours to pull.

The completed boule then undergoes wire sawing, lapping, chemical etching (alkaline or acid), CMP polishing, and cleaning to become the finished silicon wafer — approximately 775 μm thick (standard 300mm), surface roughness Ra < 0.1 nm. Each step places strict requirements on equipment and materials (especially lapping slurries, polishing fluids, and cleaning chemicals).

Epitaxial wafers (Epi-Wafers) are a higher-value silicon wafer category: a high-quality silicon epitaxial layer (2–10 μm thick) is grown on a polished wafer by CVD, used for advanced logic chips (Apple M-series, Qualcomm Snapdragon SoCs) and power devices (IGBTs). Epitaxial wafers command a price premium of 2× or more over polished wafers.

Photoresist: From Organic Synthesis to Nanometer-Scale Precision

Photoresist (PR) is a light-sensitive polymer film whose core function is to "print" the pattern from a photomask onto the wafer surface, inside a lithography tool, at nanometer precision.

The main components are: photoactive resin, photo-acid generator (PAG), and solvent. Different wavelength light sources correspond to different chemical systems:

— g-line (436nm Hg lamp): DNQ-based photoresist, resolution ~0.8 μm, widely used in packaging and mature nodes; — i-line (365nm Hg lamp): Same DNQ system with improved formulation, resolution ~0.5 μm, still widely used in 8-inch and 12-inch mature-node fabs; — KrF (248nm): Chemically amplified resist (CAR), resolution ~0.25 μm, mainstream in high-volume 12-inch mature-node fabs; — ArF dry (193nm): CAR system, resolution ~0.13 μm; — ArFi (193nm immersion): Effective wavelength reduced to ~134nm via DI water immersion, resolution ~0.09 μm, currently the workhorse for 7nm to 14nm production; — EUV (13.5nm): Metal-oxide (e.g., tin-based) or organic photosensitive system, resolution <10nm, used in 3nm and below processes; commercially available from only 3–4 global suppliers.

Each generational wavelength step requires a fundamental redesign of the entire chemical system — simple formulation adjustment is insufficient. This is why photoresist technology barriers are so high: it requires 3–5 years of co-development with specific lithography tool platforms and specific process nodes.

Electronic Chemicals: The "Blood" Running Through the Fab

Wet electronic chemicals (ultrapure H₂SO₄, H₂O₂, HF, NH₄OH, IPA, etc.) serve as cleaning agents, etchants, and developers throughout the wafer fabrication process. Their purity grades (SEMI G1–G5, with G5 being the most stringent at metallic impurities <10 ppb) directly determine whether they can be used in advanced node manufacturing.

Sputtering Targets: Purity and Grain Structure as Key Differentiation

Sputtering targets (Al, Cu, Ti, Co, Ta, W, etc.) are consumed in PVD (physical vapor deposition) processes to deposit metal films on wafers for interconnect and contact layers. The key technical parameters are chemical purity (5N to 6N, i.e., 99.999%–99.9999%) and microstructural grain size uniformity (grain size < 100 μm for fine-grained targets, essential for uniform film deposition at advanced nodes).

CMP Materials: The Art of Polishing Flat

Chemical Mechanical Planarization (CMP) is used more than 30 times in advanced logic chip manufacturing to globally planarize the wafer surface. It involves two material consumables: CMP slurry (abrasive particles + oxidizer + additives in liquid form) and CMP polishing pads (microporous polyurethane structures that hold and distribute the slurry).

Photomasks: The "Master Template" of the Chip

A photomask (reticle or mask) is a high-purity fused quartz plate coated with a chromium film, on which the circuit pattern is written by an electron beam lithography (EBL) tool. During lithography, UV or EUV light passing through (or reflecting from) the mask pattern exposes the photoresist on the wafer below.

Packaging Substrates and Auxiliaries: The New Value Frontier

Advanced packaging substrates (for CoWoS, HBM, SoIC) require line widths/spacings (L/S) as fine as 2–5 μm, 16–32 layers, ultra-low dielectric loss (Df < 0.005), and CTE matching silicon (~3–4 ppm/K). These requirements make advanced packaging substrate manufacturing a semi-semiconductor process, bridging traditional PCB fabrication and wafer-level manufacturing.

Chapter 2　Global Competitive Landscape: Japanese-Korean Duopoly, One German-American Axis, and One Multipolar Era

Shin-Etsu Chemical: The Pinnacle of Global Silicon Wafer Dominance

Shin-Etsu Chemical (TYO: 4063) is the world's largest silicon wafer supplier, with a global market share of approximately 32–35% in 12-inch (300mm) wafers in 2025. Its semiconductor division revenue approached JPY 3.2 trillion (~USD 21 billion) in FY2025, driven by 300mm silicon wafers and organic silicones.

Shin-Etsu's competitive moat lies in its vertical integration across the entire silicon element value chain: high-purity polysilicon → single-crystal growing → wafer polishing → epitaxial deposition, plus organic silicones (Silicone) and PVC stabilizers. This cross-domain "silicon" industrial portfolio gives Shin-Etsu unmatched engineering experience in silicon purification, crystal growth, and surface treatment — a 40-year accumulation that is fundamentally difficult to replicate.

In photoresist, Shin-Etsu is one of the core developers of EUV photoresist. Its metal-organic photoresist (MORP) system, based on tin-oxide chemistry, is reported to offer superior line-edge roughness (LER) compared to competitors, and is under active evaluation by TSMC for its N2 and N2P nodes.

SUMCO: The Twelve-Inch Wafer's Enduring Challenger

SUMCO (TYO: 3436) is the world's second-largest silicon wafer supplier, with a global 300mm market share of approximately 25%. Its Q4 2025 revenue reached JPY 105.2 billion, modestly above expectations, though it reported an operating loss of JPY 4.5 billion due to ongoing 200mm capacity rationalization. SUMCO is strategically pivoting away from 200mm (where Chinese competition is intensifying) and doubling down on AI-grade 300mm wafers (ultra-flat, ultra-low metallic contamination), where pricing remains significantly more favorable.

JSR: Japan's Government-Backed Photoresist Champion

JSR (now privatized, formerly TYO: 4046) is one of the world's top 2 semiconductor photoresist suppliers, covering KrF, ArF, ArFi, and EUV photoresist across all process nodes. Japan's privatization of JSR in 2023–2024 via JIC (Japan Investment Corporation) was among the most strategically significant moves in the semiconductor materials industry in recent years — effectively placing JSR's supply policy under Japanese government influence.

For China's domestic semiconductor materials industry, JSR's privatization signals that even without formal export controls on photoresist, JSR's supply decisions are now within the orbit of Japanese policy — a source of long-term supply chain uncertainty.

Tokyo Ohka Kogyo (TOK): The Quiet Expert Behind Immersion ArF

TOK's competitive strength lies in its deep co-development relationships with TSMC and Samsung for ArF immersion (ArFi) photoresist. Its resist chemistry is optimized specifically for the 193nm immersion exposure system and the tight process windows of 7nm–3nm logic nodes. TOK's business model of "deep process alignment with a small number of tier-1 customers" makes it extremely difficult to displace, even as Chinese competitors develop technically equivalent products.

Merck KGaA: The European Chemicals Giant's Materials Portfolio

Merck KGaA (XETRA: MRK) is Europe's leading semiconductor materials conglomerate, covering liquid crystals (display), specialty chemicals (etch residue removal agents), ALD/CVD precursors, and EUV lithography ancillary materials. Its semiconductor solutions division posted revenue of approximately EUR 1.7 billion in FY2025, growing ~12% year-over-year.

Entegris: The Advanced Materials Systems Platform Company

Entegris (NASDAQ: ENTG) is not a monolithic material supplier but a multi-product materials and process control platform serving advanced semiconductor fabs. Its product lines include CMP slurries and pads (via CMC Materials acquisition, USD 6.5 billion in 2022), specialty filtration (liquid and gas purification), advanced process chemicals, and materials handling systems (wafer carriers, reticle pods, high-purity containers).

Cabot Microelectronics (CMC Materials): The CMP Slurry Global Leader

CMC Materials holds approximately 40–45% global share of the CMP slurry market. Its competitive moat is three-layered: patent barriers (2,000+ patents covering abrasive types, oxidizer combinations, surfactant formulations), process binding (CMC's slurry formulations are co-optimized with specific fab processes at TSMC/Samsung, making switching extremely costly), and global service network (local engineering teams at all major fab clusters in Taiwan, Korea, Singapore, and the US).

Against Anji Microelectronics' growing challenge, CMC's strategy is to maintain technology leadership in the most advanced nodes (sub-2nm) while accepting measured market share loss in mature nodes to cost-competitive Chinese competitors.

Global Competitive Landscape: Certification Cycles and Data Validation

The key data point for global semiconductor materials market share: the global market grew from approximately USD 65 billion in 2024 to an estimated USD 72–74 billion in 2025, with China's domestic market growing faster than average (approximately 18–22% growth vs. ~7–9% globally) due to fab capacity expansion and domestic content policy.

Ulvac and Materion: The Niche Target Specialists

Ulvac (Japan) and Materion (US) represent the niche specialists in the sputtering target space — Ulvac focuses on ultra-high-purity metal evaporation sources and specialty target alloys (cobalt, manganese, ruthenium for advanced barrier layers), while Materion has strong capabilities in precious and refractory metal targets (gold, platinum group metals, tungsten, molybdenum) used in specialty process steps.

Wet Electronic Chemicals: Global Leaders Include BASF and Stella Chemifa

BASF SE (Germany) and Stella Chemifa (Japan) are global leaders in high-purity wet chemicals (HF, H₂O₂, H₂SO₄, TMAH) for semiconductor applications. The global wet electronic chemicals market is approximately USD 5.5–6.0 billion in 2025, dominated by Asian players (Japan, Korea, Taiwan) in the highest-purity grades.

Chapter 3　PEST Analysis: Export Controls Escalation + National Big Fund + Domestic Substitution Acceleration + Technology Evolution Driving Forces

Political Layer: The Systemic Nature of Export Controls

The export controls on semiconductor materials since 2022 are no longer incremental policy adjustments but systemic restructuring of global technology supply chains. Their distinctive feature is not "banning sales of finished chips" but precision targeting of upstream chokepoints — materials and equipment that China's domestic producers cannot yet replace.

The most recent significant moves: In 2022 and 2023, the US BIS progressively expanded restrictions to cover advanced chip manufacturing equipment, EDA tools, and key process materials. Japan's July 2023 controls on 23 categories of semiconductor manufacturing equipment — including advanced deposition and etch tools — represent the first time Japan formally aligned its export control regime with the US framework, closing an alternative supply route that Chinese fabs had relied upon. The Netherlands, under US diplomatic pressure, has restricted ASML's EUV lithography tool exports since early 2023.

A key structural observation: export controls on equipment and materials interact synergistically. Restricting the most advanced lithography tools (EUV) reduces the immediate commercial urgency for EUV photoresist and EUV-specific precursors in China — but also creates enormous pressure to develop domestic alternatives before EUV access constraints become a binding production bottleneck.

Economic Layer: Investment in China During the Most Competitive Era

The "National Big Fund III" (国家大基金三期, RMB 344 billion) represents the largest single-tranche government semiconductor investment in China's history. Its first deployment of RMB 164 billion in January 2025 targeted two sub-funds: one focused on equipment/materials localization (approximately 70% of total), one on advanced packaging and AI memory (approximately 30%). This capital structure reflects a deliberate shift from "build chip designers and fabs" (Fund I, II priority) to "secure upstream supply chains" (Fund III priority).

National Major Science and Technology Program (02 Special Project): Complementary to the Big Fund, 02 Project grants are direct R&D appropriations for specific technological targets — ArF photoresist qualification, EUV precursor development, 12-inch silicon wafer advanced-node verification. The "government R&D + Big Fund equity → fab purchase orders → materials company revenue" three-stage pipeline is China's systematic approach to semiconductor materials localization.

Social Layer: Supply Chain Awareness and Systemic Risk Recognition

Export controls have triggered a fundamental shift in how Chinese fabs approach materials procurement: from "buy the best global product" to "build a dual-sourcing strategy where domestic alternatives are viable fallbacks." This shift is not merely commercial risk management — it is now a board-level strategic imperative at SMIC, YMTC, CXMT, and HuaHong.

Technology Layer: The Process Node Compression Driving Materials Demand

Technology node compression drives materials requirements systemically upward: every node step (28nm → 14nm → 7nm → 5nm → 3nm → 2nm) requires higher purity, tighter particle size distribution, better process window compatibility, and more process steps (total CMP steps exceeding 30 at 3nm). This creates a powerful demand tailwind for premium materials that is almost entirely decoupled from overall economic conditions.

Chapter 4　China's Market Size: RMB 174 Billion, Structural Gaps toward RMB 280 Billion

China Is Already the World's Largest Single Semiconductor Materials Market

China surpassed Taiwan as the world's single largest semiconductor materials market in 2022 and has maintained this position since. In 2025, China's semiconductor materials market reached approximately RMB 174 billion (USD 24 billion), representing roughly 33% of the global market. This dominance reflects China's unparalleled position as the world's largest buyer of memory (DRAM: CXMT; NAND: YMTC), foundry services (SMIC, HuaHong), and advanced packaging (ASE/Amkor China operations).

Sub-Sector Market Size Breakdown

Sub-Sector	China Market Size (2025E)	Global Market Size	China Share
Silicon wafers (12-inch)	~RMB 50-55B	~USD 30B	~25%
Photoresist (all generations)	~RMB 20B+	~USD 4B	~25-28%
Wet electronic chemicals	~RMB 29.3B	~USD 6B	~28%
CMP materials	~RMB 10B	~USD 3.4B	~20%
Sputtering targets	~RMB 3.3B	~USD 4B	~12%
Photomasks	~RMB 10B	~USD 5B	~14%
Electronic specialty gases	~RMB 10B+	~USD 6.7B	~15%
Packaging substrates (advanced)	~RMB 15B	~USD 10B	~22%

Domestic Substitution Curve: Phase-by-Phase Localization Progress

China's overall semiconductor materials domestic content rate stands at approximately 30–35% in 2025, up from approximately 10–15% in 2018. The improvement reflects systematic progress across all major sub-sectors, though at markedly different rates. The fastest-improving sub-sectors (KrF photoresist: 30–40% domestic; CMP slurry: 20–25% domestic; sputtering targets: 30–38% domestic market share for domestic brands) share a common characteristic: they all began serious domestic development efforts more than 10 years ago, typically around 2012–2015, giving them a 10-year runway to build technical knowledge before the current acceleration phase.

CR5 Concentration Ratio: Decreasing but Still High

At the global level, CR5 in silicon wafers (Shin-Etsu + SUMCO + Siltronic + SK Siltron + GlobalWafers) remains above 90%. At the China domestic market level, domestic supplier concentration varies: in CMP slurry, Anji Microelectronics holds ~70–75% domestic market share among domestic brands; in KrF photoresist, Photech New Materials holds >40% of China's domestic supply. These are healthy concentration levels for companies still in scale-building phases, but they also represent supplier concentration risks for the fabs.

Epitaxial Wafers vs. Polished Wafers: Two Different Trajectories

Epitaxial wafers (epi) account for approximately 35–40% of China's 12-inch silicon wafer market by value. NSIG (Hermes-Epitek Shanghai) and TCL Zhonghuan are the primary domestic suppliers. The primary challenge for domestic epi-wafer providers is maintaining consistent electrical parameters (background doping uniformity, crystal defect density) across large production volumes — requirements that are more demanding than for polished wafers and that require tight process control over the CVD epitaxial reactor.

Investment Efficiency: Lessons from Capital Density in Silicon

The silicon wafer industry is among the most capital-intensive in semiconductor materials: a 100,000-wafer-per-month 12-inch silicon fab requires capex of approximately RMB 5–10 billion. NSIG's Shanghai base at 750,000 wafers/month capacity represents an investment of approximately RMB 8–12 billion over five years. This capital intensity means the sector has both high barriers to entry and long payback periods — making the timing of capacity additions critical for capital discipline.

The 12-Inch Ramp: Supply Catching Up to Demand

China's 12-inch silicon wafer supply-demand balance: domestic fab demand of approximately 600,000–700,000 wafers/month in 2025 vs. domestic supply capacity of approximately 145,000 wafers/month at full utilization (NSIG 75,000 + TCL Zhonghuan Central 70,000). The gap is filled by imports from Shin-Etsu, SUMCO, Siltronic, and SK Siltron. By 2027, if all announced domestic expansion plans are realized, domestic supply capacity could approach 200,000–250,000 wafers/month — still well below demand, but significantly reducing the import dependency ratio, particularly for mature-node-grade wafers.

Chapter 5　Value Chain Dissection: From Multiple Materials to Advanced Packaging — The Full Materials Map

Upstream: Raw Materials Supply Chain

The critical upstream inputs for semiconductor materials include: high-purity quartz sand (for silicon wafer crucibles, quartz process chambers); high-purity graphite (for crystal growing furnace components); specialty metals (cobalt, tantalum, ruthenium, molybdenum for advanced process targets and barrier layers); high-purity organic chemical intermediates (for photoresist polymer synthesis, precursor synthesis). The supply security of these upstream inputs varies considerably — quartz sand has significant Chinese domestic supply, while high-purity cobalt and tantalum are primarily sourced from DRC (Democratic Republic of Congo) with further refining in Japan, Korea, and Finland.

Midstream: Where the High-Value Materials Are Created

The midstream is where chemical engineering, process knowledge, and precision manufacturing combine to create the high-value products. This is the core competitive battlefield for domestic Chinese materials companies. Key competitive dimensions in midstream: purity control (how consistently can the manufacturer achieve target metal contamination levels across production lots?), particle size distribution (in CMP slurries, how tight is the abrasive particle size distribution, and how stable is it over storage?), and process window compatibility (how robust is the material's performance across variations in fab process conditions?).

Downstream: The Wafer Fab as the System Integrator

Wafer fabs (SMIC, YMTC, CXMT, HuaHong) are not merely "customers" of semiconductor materials — they are active co-developers of new materials. The co-development model: the fab's process integration team defines the material's target specifications, identifies failure modes in preliminary testing, and provides "process-coupled feedback" to the material supplier. The supplier iterates formulation based on this feedback. This tight feedback loop is the key to why materials companies co-located near major fab clusters (Shanghai → SMIC/HLMC; Hefei → CXMT; Wuhan → YMTC) have structural advantages over geographically distant competitors.

Materials-Equipment-Materials Interdependence

Semiconductor materials and equipment are deeply interdependent: a CMP slurry must be compatible with the specific platen speed, pressure profile, and polishing time parameters of the CMP tool used (Applied Materials' Reflexion platform, or EBARA's F-REX). An ALD precursor must be optimized for the specific pulse/purge timing and temperature profile of the ALD reactor (ASM International's Pulsar, or Applied Materials' Producer). This equipment-material co-optimization cycle means that changing equipment suppliers often requires re-qualifying materials — a significant switching cost that acts as a competitive moat for both equipment and materials companies.

Upstream-Downstream Dual-Supply Challenges: The Art of Balancing Domestic and International Sources

Most Chinese fabs currently operate a "dual-sourcing" procurement strategy for critical materials: a domestic supplier as primary or backup, combined with an established international supplier as quality benchmark and safety net. This approach reduces single-source risk while allowing domestic suppliers to accumulate qualification data and scale up production capacity. The challenge is that dual-sourcing requires maintaining two separate supply chains, adding administrative overhead and sometimes leading to inventory imbalances — a manageable cost during the transition to full domestic sourcing.

Chapter 6　Key Company Profiles: Fourteen Domestic Companies Plus Global Benchmarks

NSIG (688126.SH): The 12-Inch Silicon Wafer Capacity Champion

NSIG (National Silicon Industry Group, 沪硅产业) is China's leading 12-inch silicon wafer manufacturer. By end-2025, NSIG's 300mm capacity reached 750,000 wafers/month across its Shanghai (SMCI) and Taiyuan (NSIG Taiyuan) bases. Full-year 300mm wafer shipments reached 6.416 million wafers (+27% YoY). NSIG has completed 14nm-node silicon wafer R&D qualification (achieving the specification required for SMIC's N+2 process). Its 12-inch wafer revenue reached RMB 2.439 billion in FY2025.

The key technical challenge for NSIG in the near term is improving the proportion of "advanced-node-grade" wafers in its total shipments — currently, a significant portion of its 75,000 wafer/month capacity serves mature-node (28nm and above) customers. Moving the full capacity toward advanced-node-grade requires tighter oxygen control (precipitate engineering for zero-defect zones), better particle contamination management, and CMP final polish optimization.

TCL Zhonghuan (002129.SZ): The Domestic Silicon Wafer Alternative

TCL Zhonghuan (through its subsidiary Zhonghuan Leading Semiconductor) had semiconductor materials revenue of RMB 5.707 billion in FY2025 (+21.75% YoY). Zhonghuan Leading's monthly 12-inch capacity reached 700,000 wafers/month by end-2025, with expansion to 1,000,000 wafers/month planned. TCL Zhonghuan's 12-inch wafer revenue for FY2024 (the most recent full-year disclosed) was RMB 2.33 billion (+70% YoY), reflecting the rapid ramp of its Yinchuan (宁夏) 12-inch fab.

Lianying Microelectronics (605358.SH): The 12-Inch Silicon Wafer Niche Specialist

Lianying Microelectronics has achieved commercial-scale production of 12-inch silicon wafers, serving primarily mature-node fabs in China. Its competitive positioning is as a cost-competitive alternative to NSIG for non-critical (mature node) applications, with improving quality consistency as its primary growth lever.

NANDe Optoelectronics (300346.SZ): ArF Photoresist: China's Best Chance at Advanced Patterning

NANDe Optoelectronics' semiconductor materials R&D center is one of the strongest in China's photoresist sector. Its Ningbo base (500 tons/year ArF production capacity, operational by end-2025) is the largest ArF photoresist production facility in mainland China. The 14nm process qualification (ArF dry) achieved a reported yield verification rate of 99.7%.

The key technology frontier for NANDe is ArF immersion (ArFi) photoresist — required for 7nm production — where it has commercial product available but not yet at the scale and process window consistency needed for tier-1 volume production qualification. This represents NANDe's most critical technical milestone for the 2026–2027 timeframe.

Jingray Electronic Materials (300655.SZ): Full-Line Photoresist Tracker

Jingray Electronic Materials covers g-line, i-line, and KrF photoresists, with H1 2025 photoresist revenue of RMB 106 million (+18% YoY). Its strategy is full coverage of commercial-scale photoresist with cost competitiveness as the primary differentiator, rather than racing to EUV or ArFi. In mature-node (28nm and above) fabs, Jingray is a credible alternative to Japanese suppliers.

Photech New Materials (603650.SH): KrF Photoresist: the Domestic Leader

Photech's KrF photoresist domestic market share exceeds 40%, making it the clear leader in China's KrF segment. Its electronics materials revenue for H1 2025 reached RMB 442 million. The company has achieved commercial production of ArF dry and immersion photoresists as well, though at smaller scale than its KrF business. Full-year 2025 revenue: RMB 2.523 billion (+4.06%), net profit RMB 520 million (+11.46%).

Anji Microelectronics (688019.SH): CMP Slurry: China's Global Top-5 Breakthrough

Anji Microelectronics is China's most internationally competitive semiconductor materials company, with approximately 10% global market share in CMP slurry — placing it among the top 5 globally in its sub-sector. Its CMP slurry revenue reached approximately RMB 1.55 billion in FY2024. Anji has operations in Singapore and Taiwan, with Taiwan representing its most strategically important overseas market — qualifying its slurries at TSMC demonstrates the highest level of technical credibility available in the industry.

Key product lines: STI (Shallow Trench Isolation) CMP slurry (its earliest and largest volume product), tungsten CMP slurry, copper CMP slurry, and barrier CMP slurry. Its continuous improvement in "selectivity ratio" (the ratio of removal rates between different materials — critical for maintaining pattern fidelity in advanced node CMP) is the primary technical driver of its growing share at leading-edge customers.

Jiangfeng Electronics (300666.SZ): Sputtering Targets: The Global Advanced-Node Breakthrough

Jiangfeng Electronics is China's most technically advanced sputtering target company. H1 2025 revenue: RMB 2.468 billion (+28.71%), net profit RMB 352 million (+56.79%). Target revenue accounts for 68.4% of total. All top-10 global chip fabs are customers. Its 3nm target qualification at TSMC (the most demanding current production node) represents the highest-level industry certification any Chinese semiconductor materials company has achieved. Domestic market share in 16nm-and-below process targets: #1 in China. International expansion: established a production facility in Korea in 2025.

Anji Microelectronics (688019.SH): CMP Slurry: The Domestic First Mover

See Chapter 6 above — Anji Microelectronics is profiled comprehensively as the CMP slurry leader.

Dinglong Holdings (300054.SZ): CMP Pads: The Chase for Dow Chemical

Dinglong's CMP pad business: through the first three quarters of 2025, combined CMP pad/slurry/cleaning revenue of RMB 1.0 billion (37% of total revenue). Wuhan hard pad monthly capacity reached 50,000 pads in Q1 2026. The technical journey from "pass qualification" (2022) to "scale production" (2026) has been 4 years — consistent with the typical 3–5 year timeline from lab qualification to volume manufacturing.

Dinglong's pricing strategy against Dow Chemical (IC-1000 pad leader, ~70% global share): approximately 20–30% discount on equivalent products, combined with superior local service response times and reduced supply chain lead times. This TCO (total cost of ownership) advantage is the primary lever for expanding from mature-node (28nm+) customers toward advanced-node (14nm and below) customers.

Qingyi Optoelectronics (688138.SH): From Display Masks to Semiconductor Masks

Qingyi Optoelectronics holds global #4 and China #1 position in display photomasks, with FY2024 revenue of RMB 1.112 billion (+20.35%), Q1 2025 revenue of RMB 299 million (+9.83%). Its semiconductor photomask progress: 150nm node small-volume production achieved; advancing toward 90nm and 55nm qualifications. The display mask cash flow funds the long-cycle R&D investment required for semiconductor mask advancement.

Luwi Optoelectronics (688676.SH): High-Margin Semiconductor Mask Specialist

Luwi's first three quarters of 2025 revenue grew +37.25%, with gross margin of 34.61% — among the highest in China's semiconductor materials sector. Its strategy is focused on mature-node semiconductor masks at scale, building stable relationships with SMIC, HuaHong, and domestic power semiconductor fabs.

Shennan Circuits (002916.SZ) and Xingsen Technology (002436.SZ): The Advanced Packaging Substrate Pair

Shennan Circuits is China's largest commercial PCB and packaging substrate manufacturer, with advanced packaging substrate (for CoWoS-type and AI chip applications) as its fastest-growing segment. Xingsen Technology focuses on IC substrates and has been rapidly expanding its advanced-node (L/S < 30/30 μm) substrate capacity. Both companies are primary beneficiaries of the AI chip packaging supply chain buildout.

Global Benchmarks: Shin-Etsu Chemical and SUMCO's Business Models

See Chapter 2 for detailed profiles of Shin-Etsu Chemical and SUMCO. From a Chinese domestic materials company perspective, Shin-Etsu's model (vertical integration from polysilicon → wafer + organic silicone) and SUMCO's model (pure-play wafer specialist) represent two different competitive philosophies that Chinese companies can benchmark and selectively adopt.

Chapter 7　Industrial Clusters: Shanghai Leading, Hefei-Wuhan Catching Up, Seoul and Europe as Bilateral Lenses

[天下工厂产业研究院] observes that when mapping China's semiconductor materials industrial clusters, one key pattern consistently emerges: materials clusters form around major fab customers, and the density of the fab cluster directly determines the density and technical level of surrounding materials suppliers.

Shanghai: China's Semiconductor Materials Epicenter

Shanghai is the highest-density semiconductor materials cluster in China, driven by the presence of SMIC (Shanghai), HuaHong (Shanghaiese), SMEE (Shanghai Micro Electronics Equipment), and the ecosystem of equipment and materials companies attracted by these fab customers. Key companies headquartered or with major operations in Shanghai: NSIG (300mm silicon wafers), Anji Microelectronics (CMP slurry), NANDe Optoelectronics' R&D center, and numerous wet chemical and specialty gas companies.

Shanghai's multi-dimensional advantages: fab proximity (30-minute delivery radius for any fab in the Greater Shanghai area), university support (Fudan University, Tongji University, SJTU materials and chemistry programs), cleanroom infrastructure (a dense ecosystem of equipment service providers and precision cleaning facilities), and government support (Shanghai Integrated Circuit Industry Fund and the Lingang Special Zone's preferential policies).

Hefei-Nanjing-Wuhan: The Storage-Materials Axis

Hefei-Nanjing-Wuhan forms China's second-most-important semiconductor materials corridor, anchored by CXMT (Changxin Memory, Hefei), YMTC (Yangtze Memory Technologies, Wuhan), and multiple advanced packaging companies. Key materials companies in this corridor: Anji Microelectronics (Hefei user for CXMT), Yake Technology's precursor supplies (to both YMTC and CXMT), Dinglong Holdings' Wuhan CMP pad facility.

The specific material requirements of 3D NAND (YMTC's 232-layer product) and DRAM (CXMT's 19nm DDR4) create unique demand for high-aspect-ratio etch gases, deep-trench CMP slurries, and DRAM-specific precursors — materials that domestic suppliers in this corridor are specifically optimizing for.

Beijing and Northeast: Defense, Research, and Core Nodes

Beijing and China's Northeast (Shenyang, Harbin, Changchun) are relatively smaller in terms of semiconductor fab density but play important roles in defense-related semiconductor applications (CETC subsidiaries in Beijing), academic research institutions (Chinese Academy of Sciences' Semiconductor Research Institute, Tsinghua's materials programs), and legacy precision industries (carbide tooling, specialty alloys, carbon-material advanced composites) that feed into semiconductor materials.

The International Lens: Japan-Taiwan-Europe as Bilateral Penetration

Japan's semiconductor materials companies have partially adopted a "China localization" strategy — Shin-Etsu (organic silicon, Nanjing), SUMCO (local business operations), JSR and TOK (local sales and technical service teams) — creating a complex "local presence but global control" dynamic. As export control environments evolve, these "localized" operations become both assets (maintaining customer relationships) and liabilities (subject to home-country policy pressure), creating strategic ambiguity for both the Japanese companies and their Chinese customers.

Taiwan's key role: TSMC and Samsung's qualification stamps carry maximum industry credibility. Jiangfeng Electronics' 3nm qualification at TSMC, and Anji Microelectronics' Taiwan operations, both validate these domestic companies' technical capabilities in the most demanding possible environment.

Europe's bilateral dynamic: Netherlands/ASML, Germany/Merck KGaA, and Siltronic maintain varying degrees of China exposure, navigating different national export control regimes. European chemical companies (Merck, BASF) have shown somewhat greater flexibility in China engagement than their US counterparts — though this is subject to ongoing geopolitical pressure.

Chapter 8　Specialty Topics: Eight Breakthrough Windows and Emerging Market Opportunities

Topic 1: 12-Inch Silicon Wafer Advanced-Quality Breakthrough: The Long-Game Battlefield

The technical frontier for domestic 12-inch silicon wafers is not production capacity (NSIG + TCL Zhonghuan already have adequate capacity for mature nodes) but "advanced-node-grade wafer ratio" — the proportion of wafers meeting the strict specifications needed for 14nm and below logic processes and DRAM below 19nm. Achieving advanced-node-grade requires: interstitial oxygen content < 11 ppma, bulk micro-defect (BMD) density precisely engineered (not too low, not too high — to prevent sub-surface slip), surface metal contamination < 0.01 ppb (for key metals), edge profile control (edge exclusion zone <2mm), and SFQR < 50nm across the full wafer.

Topic 2: EUV Photoresist — The Hardest Technical Frontier

EUV photoresist is the technically most demanding sub-sector of semiconductor materials. The fundamental challenge: EUV photons (13.5nm wavelength, 92 eV energy) are absorbed extremely inefficiently by organic molecules (organic photoresists have low cross-sections at EUV wavelengths), requiring either much higher EUV dose (reducing throughput) or a fundamentally different chemistry.

The leading approach, pioneered by Inpria (now Merck), is metal-oxide photoresist (MOP): tin-oxide (SnO₂) nanoparticles dispersed in a solvent, which absorb EUV photons efficiently and undergo photochemical transformation. The challenge is simultaneously minimizing line-edge roughness (LER) and achieving sub-10nm resolution — the two requirements work against each other in traditional chemically amplified resist (CAR) systems.

China's EUV photoresist status: no commercially available domestic EUV photoresist in 2025. NANDe Optoelectronics and a few academic institutions are in pre-commercialization R&D stages. The timeline for domestic EUV photoresist to be commercially ready is estimated at 2028–2030.

Topic 3: Transitioning KrF and ArF from Lab to Scale Manufacturing

The domestic photoresist industry's most immediate commercial opportunity is scaling KrF photoresist from the current 40% domestic market share toward 60%+ over the next 2–3 years. The key bottleneck is no longer technology (the chemistry is proven) but manufacturing consistency: lot-to-lot CD (critical dimension) uniformity variation must be controlled within ±1nm at the 90nm process node — a specification that requires both formulation precision and manufacturing process control.

Topic 4: CMP Materials — A Nanometer-Grinding One-Inch War

The CMP materials battleground is rapidly evolving from "slurry vs. pad" binary competition to a "CMP system" competition: the combination of slurry formulation, pad type (hard pad vs. soft pad vs. fixed-abrasive), conditioning disk design, and endpoint detection all interact to determine the overall CMP process performance. Domestic companies excelling in individual CMP material elements are beginning to offer "integrated CMP solutions" — providing fab engineers with optimized material combination recommendations, not just individual material specifications.

Topic 5: High-Purity Targets — The Security of the Global Supply Chain

The most supply-chain-critical aspect of sputtering targets is not the mainstream aluminum or copper targets (where China has adequate supply) but specialty targets for advanced nodes: cobalt (Co, for contact layers in 7nm and below), ruthenium (Ru, replacing cobalt in some applications), manganese silicide (MnSi, for self-forming barriers), and molybdenum (Mo, for GAA FET gate metals). These specialty targets are produced by Materion, Ulvac, Tosoh (Japan), and Plansee (Austria) — with limited Chinese domestic supply. Jiangfeng Electronics is actively developing some of these specialty targets, but volume production qualification at leading fabs remains 2–3 years away for the most challenging compounds.

Topic 6: Semiconductor Photomasks — The Hardest Niche

Semiconductor photomasks are produced by a small number of highly specialized manufacturers: Toppan Photomasks (Japan), DNP (Japan), Photronics (USA), SK Siltron Photo (Korea), and Qingyi Optoelectronics (China). The capital intensity is high (an advanced EBL writer costs USD 10–20 million), the cycle time is long (2–4 weeks from pattern data to finished mask), and the quality requirements are extremely stringent (CD uniformity ±1nm, defect density <0.01 defects/cm²). Qingyi Optoelectronics' path to 55nm node semiconductor mask production (currently at 150nm small-volume production) requires both equipment upgrades (next-generation EBL writers) and process development, with a 2–3 year timeline.

Topic 7: Wet Electronic Chemicals — The Purity Breakthrough

China's wet electronic chemicals industry has made significant progress in Grade 4 (mature node) products but faces a technical barrier at Grade 5 (advanced node, <10 ppb total metallic impurities). The key enablers for Grade 5 domestic production: ion-exchange resin technology maturation (to selectively remove trace metals from acid solutions), advanced analytical capability (ICP-MS instruments capable of measuring sub-ppb metal contamination), and ultra-clean packaging systems (FC-HDPE containers or PTFE-lined containers that do not leach contaminants into the chemical).

Topic 8: Packaging Substrates — Advanced Packaging's Coming Wave

The Advanced Packaging substrate market is growing faster than any other semiconductor materials sub-sector. The primary driver: AI chip packaging (CoWoS for NVIDIA H/B series, Intel's EMIB, AMD's HBM packaging) requires advanced packaging substrates with L/S ≤ 5/5 μm, ultra-low dielectric loss, and CTE-matched to silicon. Shennan Circuits and Xingsen Technology are both accelerating investment in advanced packaging substrate capacity, and both have qualified at TSMC's CoWoS supply chain.

Topic 9: Precursor Materials — The Highest-Value Hidden Battlefield

ALD precursors (TDMAHf for HfO₂ gate dielectric, TDMAT for TiN barrier layers, 3DMAS for Si₃N₄ passivation, TBTDET for TaN diffusion barriers) represent high-value, low-volume materials whose strategic importance far exceeds their market size. Yake Technology is China's most comprehensive precursor supplier, covering silicon, hafnium, titanium, tantalum, and other key precursor families. As 3D NAND layer counts increase (232L → 300L → 400L) and DRAM node scaling continues, ALD process steps multiply, driving precursor volume growth.

Chapter 9　Technology Roadmap: How Materials Innovation and Process Nodes Are Jointly Evolving

12-Inch Silicon Wafers (300–400mm): The Long Future Ahead

Beyond the current 300mm mainstream, the semiconductor industry is beginning to explore 450mm (18-inch) wafers — though this transition has been "perpetually 10 years away" since Intel, TSMC, and Samsung initially proposed it around 2012. The more immediate transition is improving 300mm wafer quality toward "zero-defect" specifications for AI chip production — achieving SFQR < 20nm (vs. current <50nm standard), surface metal <0.001 ppb, and interstitial oxygen uniformity <±2% across the full wafer.

Domestic opportunity: The 450mm wafer transition, when it eventually occurs, will create a level playing field (no incumbent has volume 450mm production). Chinese companies investing in 300mm technology supremacy now are building the foundation for 450mm leadership later.

EUV Photoresist and the Chemistry/Physics Frontier

EUV lithography's fundamental challenge for photoresist: stochastic effects become significant at sub-10nm feature sizes, causing random variation in resist pattern formation that is not solvable by simply optimizing macroscale resist chemistry. The solution requires controlling the interaction between individual EUV photons and individual resist molecules — a regime where quantum chemistry and materials physics merge. This is why EUV photoresist remains a frontier research topic at major universities worldwide (MIT, Leuven, Tokyo) and why commercialization timelines are difficult to predict.

High-k Dielectrics and ALD Precursors: The Chemistry Frontier at Advanced Nodes

The gate dielectric material in advanced CMOS transistors is no longer silicon dioxide (SiO₂) but hafnium oxide (HfO₂), a high-k dielectric that allows equivalent electrical performance with a physically thicker layer (reducing quantum-mechanical leakage). The ALD precursor for HfO₂ deposition (TDMAHf, Hf[N(CH₃)₂]₄) is one of the most strategically important precursors in advanced semiconductor manufacturing. Yake Technology's qualification as a TDMAHf supplier to SMIC and YMTC represents a significant step in securing domestic supply of this critical precursor.

CMP Materials System: The Multi-Dimensional Competition

See Chapter 8 Topic 4 for detailed CMP system competition analysis. The technology roadmap for CMP extends toward: fixed-abrasive polishing pads (where abrasive particles are embedded in the pad rather than suspended in slurry — potentially reducing slurry consumption and improving polishing stability), next-generation barrier-layer slurries for RuO₂ and CoO barrier layers (required for GAA FET interconnect), and AI-assisted CMP endpoint detection (using machine learning to predict the optimal CMP endpoint from real-time optical emission spectra).

Advanced Packaging Materials: Accelerating with AI Chiplet Proliferation

The advanced packaging materials roadmap is driven by the chiplet (die-to-die interconnect) revolution. As AI chips migrate from monolithic dies to multi-die Chiplet architectures (HBM memory stacks + logic dies + I/O dies), the packaging substrate must provide extremely high-density, low-loss die-to-die interconnects. The material requirements for these substrates (ultra-low Df, CTE < 3 ppm/K, embedded passives) are pushing domestic packaging substrate companies (Shennan, Xingsen) to invest in novel dielectric materials and semi-additive process (SAP) manufacturing capabilities.

Atomic Materials Advances: CMP's Next Challenges

Atom-scale CMP challenges emerge at sub-5nm nodes: conventional CMP removes material at the rate of nanometers per second, which is incompatible with the Angstrom-level control required for ultra-thin dielectric layers (sub-1nm HfO₂). This creates demand for "atomic layer etching" (ALE) and "ultra-soft CMP" processes — where the slurry's chemical selectivity dominates over mechanical abrasion. Anji Microelectronics and Dinglong Holdings are both investing in next-generation slurry and pad chemistries to address these emerging requirements.

Encapsulant and Underfill Materials: Advanced Packaging's Thermal Management Challenge

As AI chip TDPs (Thermal Design Power) exceed 700W (NVIDIA GB200 at ~1000W TDP), advanced packaging encapsulants and underfills must handle extraordinary heat flux. The thermal conductivity requirement for advanced packaging underfill (at the interface between high-power AI chips and the substrate) is increasing from ~1 W/m·K (current organic baseline) to potentially 5–10 W/m·K (via thermally conductive filler loading). This creates a new materials development challenge at the intersection of thermal management and fine-pitch packaging mechanics.

Packaging Substrate Materials: Advanced Packaging Roadmap

See Chapter 5's advanced packaging substrates analysis. The 2026–2030 packaging substrate roadmap for domestic Chinese companies: L/S from current 10/10 μm → 5/5 μm → 2/2 μm; layer count from 16 → 24 → 32; dielectric material from standard low-Dk resins → ultra-low-Dk photosensitive polymers (for finer line pattern resolution without full photolithography tooling).

Semiconductor Materials and the Broader Manufacturing Future: A Preliminary Forecast

The convergence of AI hardware demand, export control pressure, and domestic policy support creates a high-confidence trajectory for China's semiconductor materials industry. The specific outcome depends on which of the scenario pathways described in Chapter 12 prevails — but in all scenarios, the directional trend toward higher domestic content rates, more sophisticated domestic suppliers, and deeper fab-materials co-development is clear.

Chapter 10　Risk Map: Geopolitical, Technical, and Market Risks

Risk 1: Further Export Control Escalation — Difficult to Predict, Potentially Non-Linear

The most difficult risk to quantify is the potential for additional, unexpected export control actions. The 2022 BIS expanded controls, Japan's 2023 23-category equipment controls, and the Netherlands' ASML EUV restrictions all occurred faster and with broader scope than most industry analysts predicted. A similar escalation targeting specific materials (EUV precursors, specific etch gases, certain semiconductor-grade metals) could create acute supply disruptions for specific Chinese fabs with limited domestic alternative availability.

Risk 2: Customer Concentration and Fab Capex Volatility

Semiconductor materials companies face inherent customer concentration risk. Anji Microelectronics' top-5 customers (SMIC, HuaHong, YMTC, CXMT, SK Hynix) account for >60% of revenue. Any single major customer reducing capex (as all major fabs did in 2023 during the industry downturn) creates direct revenue pressure. This customer concentration risk is a systemic factor in semiconductor materials company valuations.

Risk 3: Technology Path Selection Uncertainty

Domestic companies must make R&D investment decisions today about which materials technologies to prioritize — decisions based on the anticipated technology roadmaps of their fab customers, which are themselves uncertain. Investing heavily in ArF immersion photoresist infrastructure (2 years before commercial volume qualification) vs. EUV photoresist R&D (5 years before commercial viability) represents a strategic allocation decision with high uncertainty on both ends.

Risk 4: Over-Investment and Internal Competition Risk

As National Big Fund III capital floods into the semiconductor materials sector, there is a risk of redundant investment in similar technical approaches. Multiple companies simultaneously developing KrF photoresist, 12-inch silicon wafers, or CMP slurries — using similar technical approaches — may lead to temporary oversupply and margin compression once all capacity comes online. The solar polysilicon and silicon wafer industries' 2023–2024 margin collapse is a cautionary precedent: capital investment far exceeding demand forecasts led to severe overcapacity and industry-wide losses.

The mitigation: semiconductor materials' qualification barriers are higher than solar, creating natural friction against rapid market entry. But this friction is not infinite — as domestic materials technology matures and certification becomes more routine, the risk of internal competition intensifying is real.

Risk 5: Raw Materials Supply Chain Vulnerabilities

Some critical raw material inputs for semiconductor materials are themselves supply-chain-constrained: rare earth metals (for certain polishing particle applications), ultrapure xenon and krypton (for specialty etch gases and ion implant sources), and high-purity germanium (for certain specialty applications). These inputs are globally sourced from a small number of producers, and supply disruptions (whether from geopolitical events, natural disasters, or production accidents) could propagate through to semiconductor materials supply.

Risk 6: Price Volatility — The Asymmetric Risk

Unlike most industrial materials where demand-driven price declines are the primary risk, semiconductor materials face both downside price risk (from domestic oversupply) and upside price risk (from supply chain disruption). The upside risk is particularly asymmetric for fabs: a 30% price increase in a critical material (e.g., ArF photoresist) is manageable; a complete supply interruption (even for 2–3 months) could force production line shutdowns, costing far more than the material price increase would have.

This asymmetric risk dynamic is a core justification for the "domestic backup supply" strategy that Chinese fabs are adopting for critical materials — even at some cost premium — to maintain supply resilience.

Chapter 11　2026–2030 Forecasts: The Roadmap from 30% to 50% Domestic Content Rate

Baseline Forecast Assumptions

The baseline forecast (50% probability scenario) assumes: export controls remain at roughly current levels with incremental tightening; domestic fab capacity expands as planned (SMIC +30%, YMTC +50%, CXMT +100% by 2030 vs. 2025); domestic material suppliers achieve their technology roadmap milestones with typical 12–18 month delays from plan.

Sub-Sector Domestic Content Rate Forecasts

Sub-Sector	2025 Estimated Domestic Rate	2030 Forecast (Base Case)	Key Enabler
12-inch silicon wafers	15–20%	40–50%	NSIG/TCL Zhonghuan capacity expansion + advanced-node grade improvement
KrF photoresist	30–40%	50–60%	Photech/NANDe scale-up + fab procurement policy
ArF/ArFi photoresist	2–5%	15–20%	NANDe Ningbo base + new entrants
CMP slurry	20–25%	35–45%	Anji scale-up + product line extension
CMP pads	10–15%	30–40%	Dinglong Wuhan capacity ramp + new entrants
Sputtering targets	30–38%	45–55%	Jiangfeng + advanced-node qualification spread
Wet electronic chemicals	G5 <20%	G5 30%	Purity technology breakthrough + ICP-MS investment
Electronic specialty gases	15–20%	30–35%	Specialty gas company scale-up + rare gas purification
Semiconductor photomasks	10–15%	25–30%	Qingyi/Luwi advanced node extension
Advanced packaging substrates	30–40%	50–60%	Shennan/Xingsen CoWoS qualification + capacity

Key Inflection Points for Major Market Impacts

The most impactful single inflection point in the 2026–2030 timeframe would be: a domestic ArFi photoresist achieving full production qualification at SMIC's most advanced node. This would signal that Chinese domestic materials can support the full manufacturing chain for the most advanced logic chips currently producible in China — a milestone comparable in significance to Jiangfeng's 3nm target qualification.

AI Hardware Demand as a Materials Demand Multiplier

AI accelerator chip manufacturing (NVIDIA-equivalent or domestic substitutes like Cambricon, Biren, Hygon) is disproportionately materials-intensive: approximately 150–170 lithography layers (vs. 20–50 for mature-node chips), 30+ CMP steps, and CoWoS advanced packaging requiring premium substrate materials. The continued growth of AI hardware procurement (China-based data centers are among the world's largest buyers of AI accelerator chips) creates a sustained premium materials demand tailwind that is decoupled from broader semiconductor cycle dynamics.

CR5 Domestic Concentration Trends

As the domestic materials industry scales, CR5 concentration among domestic suppliers is expected to evolve: in mature sub-sectors (KrF photoresist, CMP slurry), domestic CR3 is likely to stabilize at 60–70%, with the top 2–3 players capturing the bulk of volume growth. In newer sub-sectors (EUV photoresist, specialty targets, advanced packaging dielectrics), CR5 among domestic players is likely to remain high (>80%) for several years, as only 1–2 domestic companies achieve commercial production capability at all.

Policy Tailwinds and Market Forecast Scenario Matrix

The three-scenario market forecast for China's domestic semiconductor materials industry (domestic supplier revenue only) in 2030:

Optimistic scenario (30% probability): Domestic supplier revenue reaches RMB 120–140 billion (from current ~RMB 60 billion), implying a 2025–2030 CAGR of approximately 15%.

Base case scenario (50% probability): Domestic supplier revenue reaches RMB 85–100 billion, implying CAGR of approximately 9–11%.

Pessimistic scenario (20% probability): Domestic supplier revenue reaches RMB 65–75 billion (CAGR ~2–4%), reflecting export control escalation and fab capex slowdown.

Investment Opportunity Windows

Key investment timing windows for the 2026–2030 period: 2026–2027 marks the KrF photoresist domestic share inflection (above 50%); 2027–2028 marks ArF dry photoresist commercial-scale breakthrough; 2029–2030 is the potential EUV photoresist commercialization window if domestic EUV lithography tools become available.

Chapter 12　Conclusions: The Semiconductor Materials Layer Is Rising — And This Is the Most Critical Chapter in China's Chip Autonomy Story

Standing at the intersection of multiple turning points, China's semiconductor materials industry is experiencing a transition of unprecedented scale and speed — from "managed dependence" toward "strategically resilient domestic supply." The national strategic intent is clear; the capital resources are being deployed at scale; and the technical workforce, while still developing in depth, is growing in capability faster than any prior generation.

Jiangfeng Electronics' 3nm target qualification, Photech New Materials' 40%-plus KrF domestic market share, Dinglong Holdings' rapid CMP pad volume ramp, and Anji Microelectronics' direct competition with Taiwan, Korea, and Singapore customers — these are not isolated anecdotes of bright spots in an otherwise bleak landscape. They are frontier milestones of an industry that has already crossed multiple thresholds and is now accelerating.

The Pace and Quality of Localization: Volume Production Capability and Process Stability

China's domestic semiconductor materials face a core challenge not only in technical capability but in sustained production consistency — the ability to maintain exact material specifications across thousands of repeated production batches at high volume. Semiconductor manufacturing is among the world's most demanding continuous process industries.

For materials companies, product specification compliance in a spec sheet is only the entry ticket; the real test is continuous supply for one, two, three years, with every batch meeting specification without any "excursion batch" that shifts the fab's process window. This long-term supply stability is a separate, critical capability that domestic materials companies must develop after achieving technical breakthrough.

In this regard, domestic leaders are accumulating rapidly: Anji Microelectronics has delivered continuously to SMIC and YMTC for more than five years, accumulating thousands of batch supply records; Jiangfeng Electronics' TSMC supply has continued for multiple years, with the 3nm target certification itself being proof of sustained supply capability; Dinglong Holdings' CMP pad production from 2022 validation to 2026 monthly capacity of 50,000 pads represents four years of volume manufacturing accumulation.

Supply Chain Security and the Strategic Significance of Materials Localization

From a national strategy perspective, semiconductor materials localization is not merely "revenue growth" in economic terms — it is foundational infrastructure for national supply chain security. A chip involves dozens of materials; a wafer fab depends on stable supply of hundreds of chemicals. If any single critical material is interrupted, the entire production line may stop.

This "one failure point disrupts the whole system" characteristic of semiconductor supply chains means that materials security cannot be comprehensively solved through inventory stockpiling alone (stockpiles have limits, and some chemicals have shelf-life constraints) — it can only be fundamentally resolved by building domestic supply capability.

[天下工厂产业研究院] maintains that China's semiconductor materials localization journey is one of the most strategically significant components of China's systemic manufacturing upgrade. Silicon wafers, photoresist, CMP materials, and sputtering targets — each breakthrough in these four most critical sub-sectors adds another layer of protection to the self-reliance and controllability of the entire supply chain. This is a strategic chess game measured in decades, and the current period is its most critical phase.
