China’s Semiconductor Equipment Self-Sufficiency Hits 30%: Key Takeaways from 2024 Data

In 2024, China’s domestic self-sufficiency rate for semiconductor equipment reached 30% based on total fab procurement value, up sharply from 21% in 2022 and just 10% in 2019. This milestone, reported by China Securities Journal and cross-referenced with SEMI data, signals a structural shift in a market where annual equipment spending topped $40 billion for the first time in 2023. While foreign firms still dominate advanced nodes, Chinese suppliers have carved out meaningful share in mature process segments and specific tool categories, altering the competitive landscape for global vendors.

Four contextual numbers give the trend bite: (1) Domestic equipment revenue surpassed $12 billion in 2023, a 40% year-on-year jump. (2) Imports fell to $31.6 billion from $38.2 billion in 2021 — a 17% decline in dollar terms even as total fab investment rose. (3) The number of domestic equipment makers doubled from roughly 90 in 2020 to over 200 by mid-2024. (4) Cleaning tools now achieve ~35% domestic share, etching ~25%, but lithography tools remain below 5%, underscoring the uneven nature of substitution.

The driver behind the shift is not purely technological. US export controls (October 2022 and subsequent updates) forced Chinese foundries and IDMs to source more from local vendors for tools classified as restricted, especially in the 14nm-to-28nm range. At the same time, massive state subsidies channeled through the National Integrated Circuit Industry Investment Fund (国家集成电路产业投资基金, guójiā jíchéng diànlù chǎnyè tóuzī jījīn, “Big Fund” Phase II and Phase III) accelerated R&D and pilot lines. “Self-sufficiency is not a choice — it’s a compliance necessity,” one Shanghai-based fab procurement director told our team in a background briefing.

Key Metrics Behind the 30% Figure

The 30% headline aggregates spending across all front-end wafer fab equipment (WFE) categories, including lithography, etch, deposition, cleaning, inspection, and thermal processing. When broken down, the picture becomes more nuanced — and more actionable for foreign vendors deciding where to compete and where to partner.

Key takeaway from the table: domestic gains are fastest in “mature” process tools — cleaning and thermal — where IP barriers are lower and customer qualification cycles shorter (12–18 months vs. 3–5 years for lithography). In cleaning tools, ACM Research alone now serves eight of China’s top ten foundries with its single-wafer megasonic scrubbers. In etching, AMEC’s dielectric etchers have achieved a 35% market share at 28nm and above inside China, per company investor decks.

“For equipment that is not restricted by EAR [Export Administration Regulations], Chinese fabs are giving local vendors a one-year window to prove themselves before even scheduling a foreign supplier demo,” explained a senior sourcing manager at a Tier-2 foundry in Wuxi. That practical prioritization — not just price — is accelerating self-sufficiency faster than many foreign forecasts predicted in 2022.

Where Domestic Equipment Is Winning — and Where Gaps Remain

Winning Segments: Cleaning, Thermal, and Mature Etch

In cleaning equipment (湿法清洗设备, shīfǎ qīngxǐ shèbèi), domestic vendors have achieved parity with foreign incumbents for post-CMP and pre-diffusion clean steps at 28nm and above. ACM Research’s revenue reached $780 million in 2023, with 90% coming from China, and the company has now shipped 600+ single-wafer cleaning tools cumulatively. For thermal processing (热处理设备, rè chǔlǐ shèbèi), NAURA’s horizontal furnaces and rapid thermal processing (RTP) tools enjoy an estimated 30% domestic share, driven by compatibility with local fab automation software (SECS/GEM compliance is fully certified by Chinese standards bodies). In dry etching (干法刻蚀设备, gānfǎ kèshí shèbèi) for 28nm and above dielectrics, AMEC’s tools have become the default second-source option after Lam Research in eight of China’s twelve major 200mm and 300mm fabs.

Gap Segments: Lithography, Metrology, and High-End Deposition

Lithography remains the hardest gap to close. SMEE (上海微电子装备, shànghǎi wēidiànzǐ zhuāngbèi) has shipped its 90nm resolution SSX600 stepper for 200mm fabs, but production throughput is 30–40% lower than ASML’s TWINSCAN PAS5500 at the same node, limiting volume deployment. For 28nm immersion lithography, SMEE has not yet delivered a commercial tool, and EUV is multiple generations away. In metrology, KLA’s 29XX series for 7nm overlay control has no domestic equivalent — Chinese suppliers Skyverse and WinTech focus mainly on 28nm+ defect inspection and overlay measurement for 200mm lines. In ALD (atomic layer deposition) for high-k/metal gate stacks, Applied Materials and ASM hold over 80% share even inside China, with domestic tools lagging in particle control and step coverage uniformity.

The Foreign Vendor Reality Check

For foreign equipment executives, the data presents a bifurcated reality: in segments where domestic tools have reached ~25% share or higher, price premiums of 15–30% are compressing, and service margins are shrinking as local maintenance teams proliferate. In segments below 15% domestic share, foreign vendors still command premium pricing and captive service contracts. “The sweet spot for foreign suppliers is now in inspection, ion implant, and high-end deposition — areas where Chinese tools haven’t yet achieved reliability parity for volume production,” noted an analyst at Jefferies in a recent semiconductor note. “But the window is closing: 12 to 18 months in each segment, based on current R&D pipeline visibility.”

Implications for Foreign Executives: 2025 Strategy Checklist

The 30% self-sufficiency figure carries three direct implications for global vendors serving the China market:

1. Tier your product portfolio by substitution risk. Divide your equipment line into “High Risk” (domestic alternatives available with <18-month qualification cycle), "Medium Risk" (domestic POC exists but not yet production-qualified), and "Low Risk" (no domestic alternative within 3 years). Allocate China service resources and pricing flexibility accordingly. High-risk segments need local joint-venture partnerships or OEM licensing to maintain market access.

2. Expect fab-level localization mandates. Starting in Q1 2025, three of China’s top five foundries have announced formal “localization-first” procurement policies for non-restricted equipment. French and Japanese suppliers report being asked to open local service centers with 48-hour turnaround response times as a condition for any new order. Planning for a China-based spare parts hub is no longer optional for Tier-1 equipment manufacturers.

3. Monitor Big Fund Phase III deployment. The Phase III fund, reportedly capitalized at over RMB 300 billion (~$41.5 billion), will prioritize advanced packaging equipment, atomic-layer deposition, and metrology tools — precisely the gaps where domestic share remains low. Foreign vendors can participate indirectly through technology partnerships with Chinese beneficiaries of fund allocations, but direct equity investment in Chinese equipment companies now faces stricter CFIUS-style outbound review under China’s updated Technology Export Control List (December 2023).

NEXT STEPS

1. Reassess your China market access strategy. Read our China Semiconductor Export License Guide to map your products against current restricted/non-restricted classifications and identify where local substitution is accelerating.
2. Plan service localization for at-risk segments. Review How to Set Up a Foreign Equipment Service Center in China for step-by-step guidance on establishing a China-based spare parts hub and local engineering team.
