Thesis Article: China’s Wafer, Equipment, and Lithography Progression. Wafer Companies, Building Equipment, and the Race for Semiconductor Self-Sufficiency

Abstract

From 2019 to 2026, China’s semiconductor industry shifted from importing tools to building a domestic ecosystem. Driven by U.S. export controls, Chinese wafer companies and equipment makers accelerated development in lithography, etch, deposition, and process control. While a gap remains with ASML and TSMC, China has achieved functional DUV immersion, scaled domestic equipment supply, and set targets for EUV by 2030.


1. The Landscape: Wafer Companies and Fabs Leading China

Core Wafer Manufacturers

  • SMIC – China’s largest foundry. Testing domestic tools and pushing 7nm/5nm via DUV multi-patterning. Founder Zhang Rujing stated SMIC bought 800+ machines from AMEC.
  • Hua Hong, CXMT, YMTC – Focus on mature nodes, memory, and power. Beneficiaries of domestic equipment scale-up. 3b5462c0

China has been the world’s biggest buyer of wafer fab equipment for 2 years. In 2024 it purchased $41 billion, 40% of global sales. 4009

2. Building Equipment: The Domestic Ecosystem 2019-2026

Export controls starting in 2019 forced localization. By 2026 Chinese suppliers cover almost every process step: deposition, etch, cleaning, metrology. f572

Key Chinese Equipment Companies:
Company | Focus | Progress 2019-2026
NAURA Technology | Etch, PVD, CVD, furnace, cleaning | Largest domestic equipment maker. Revenue 29.8B yuan in 2024, 5x vs 2020
AMEC | CCP/ICP etch, TSV, MOCVD | Covers 30% of IC equipment categories. Aims for 60% in 5-10 years. Etch tools now support 5nm/3nm
SMEE | Lithography DUV | Most advanced: SSA600 90nm. Developing SSA800 28nm, SSA900 22nm
Yuliangsheng / SiCarrier | Immersion DUV, future EUV | Delivered 3 DUV immersion tools to fabs. Working on EUV “Mount Everest”
ACM Research, Hwatsing, Kingsemi, Piotech | Cleaning, CMP, track, ALD | Top 30 global equipment suppliers

Self-sufficiency for 7nm and below equipment is still <10%, but for cleaning and resist removal it’s ∼50%. 4009

3. Lithography Machine Progression: The Core Bottleneck

Lithography “prints” circuits on wafers. This is where China faced the hardest block.

The External Constraint

  • 2019: US began restricting ASML EUV sales to China.
  • 2023: US also blocked advanced immersion DUV.
  • ASML remains the only EUV maker, $300M per machine, shipping 60 in 2026 and 80 in 2027. 40094d87

China’s Domestic Response

Phase 1: 2019-2022 – Rely on Old DUV
Fabs used older ASML DUV, second-hand imports, and SMEE 90nm tools. SMEE SSA600 = 90nm resolution. f78f9cc7

Phase 2: 2023-2025 – Immersion DUV Breakthrough
SMIC began testing Yuliangsheng’s domestic immersion DUV in 2024-2025.

  • Specs: 28nm-class single exposure.
  • Capability: With multi-patterning can reach 7nm, possibly 5nm at low yield.
  • Cost/Yield issue: SMIC 5nm wafers via DUV may cost 50% more than TSMC with yields as low as 33%.
  • Supply chain: Mostly Chinese parts, but some still imported. Goal is full localization.
  • Benchmark: Similar to ASML NXT:1950i from 2008, designed for 32nm. 73c63b5434c4

Phase 3: 2026-2030 – Targeting EUV

  • SMEE: Developing SSA800 28nm, SSA900 22nm.
  • SiCarrier/Yuliangsheng: Working on China’s first EUV tool codenamed “Mount Everest”.
  • Analyst view: Even if SMIC integrates 28nm immersion DUV by 2027, sub-10nm will need redesigned scanners and likely won’t be domestically made before 2030. 9cc7f78f3b54

4. Latest Components in Semiconductor Projects

A modern fab needs 3,000+ tools. China’s 2019-2026 build-out focused on: 4009

A. Patterning: SMEE DUV, Yuliangsheng immersion DUV. EUV still in R&D.
B. Etch: AMEC’s VHF decoupled plasma etch, supporting 5nm/3nm.
C. Deposition: NAURA CVD/PVD/ALD, AMEC MOCVD gaining global share.
D. Cleaning/Wet: ACM Research, Kingsemi.
E. Metrology/Inspection: Raintree Scientific.
F. CMP and Edge Polish: Hwatsing. 62c03456

AMEC aims to complete 20 types of restricted thin-film equipment soon, and 40 by 2029. f572

5. Significance and Challenges

Significance

  1. Self-reliance: The 2019 sanctions catalyzed a domestic supply chain. Gap with leaders is “continuously narrowing”.
  2. Scale: China’s fab spending dominance funds local equipment makers.
  3. Technology: Breakthroughs in immersion DUV and etch show capability to replicate, then iterate. f572

Challenges

  1. Lithography gap: Still 2-3 generations behind ASML. No EUV in production.
  2. Yield and cost: DUV multi-patterning for 7nm/5nm is expensive and low yield.
  3. Components: Some critical lenses, lasers, optics still imported. f5723b544d87

6. Conclusion: 2019-2026 as a Foundational Era

2019-2026 was not about catching ASML in EUV. It was about survival and building the base.

China moved from <20% equipment coverage to near-complete process coverage except advanced lithography. SMIC’s testing of domestic immersion DUV and the emergence of NAURA, AMEC, SMEE in the global top 30 signal this shift. 73c6f572

The next 5 years will determine if “Mount Everest” EUV and SSA800/900 DUV can close the gap for sub-7nm. For now, China’s strategy is: dominate mature nodes with domestic tools, and use DUV ingenuity to push advanced nodes until EUV arrives.

As analyst Lin Qingyuan put it: if successful, this breakthrough lets Chinese companies build more advanced machinery. f78f

China’s Semiconductor Industry (2019–2026): Wafer Companies, Manufacturing Equipment, Components, and Lithography Machine Development

Executive Summary

Between 2019 and 2026, China’s semiconductor industry underwent one of the fastest industrial transformations in modern history. Triggered by export controls, supply-chain disruptions, and the strategic goal of semiconductor self-sufficiency, China invested hundreds of billions of yuan into virtually every layer of the semiconductor ecosystem—from silicon wafers and fabrication equipment to electronic design automation (EDA), process chemicals, advanced packaging, and lithography.

Despite substantial progress, China has not yet achieved full independence in the most advanced semiconductor technologies. Strong gains have occurred in mature-node manufacturing, etching, deposition, cleaning, and wafer production, while EUV lithography remains beyond commercial domestic capability. DUV lithography, advanced packaging, and mature-node fabrication have become major strengths. (South China Morning Post)
