Key Takeaways
- A state-funded Shanghai firm has initiated mass production of domestically developed immersion DUV lithography equipment for the first time.
- ASML shares plummeted more than 7% following the announcement, wiping out a 2% pre-market rally.
- American semiconductor equipment manufacturers Applied Materials (AMAT), Lam Research (LRCX), and KLA Corp (KLAC) experienced declines of 4–7% in tandem.
- The Chinese-made DUV systems remain in early production phases — the manufacturer targets only 5 units in 2024 and approximately 20 by 2027.
- This advancement puts ASML’s final significant Chinese revenue stream at risk, as DUV equipment sales compensated for prohibited EUV exports.
A government-supported Shanghai manufacturer has launched mass production of indigenous immersion DUV lithography systems — sending shockwaves through semiconductor equipment stocks.
ASML shares tumbled over 7% Monday following The Information’s exclusive report. The Netherlands-based semiconductor equipment leader had climbed more than 2% in pre-market trading, buoyed by diminishing Iran-related geopolitical tensions and reports of Nvidia’s potential involvement in a $250 billion OpenAI data center project. Those gains vanished quickly.
Investor anxiety over ASML’s China operations has persisted for months. During the company’s Q2 earnings presentation, China represented 14% of net system revenues, declining from 19% the previous quarter. CFO R.J.M. Dassen projected China would comprise roughly 20% of annual net sales. That projection now appears uncertain.
After American and Dutch export restrictions prevented ASML from delivering cutting-edge EUV systems to China, Chinese semiconductor manufacturers responded by accumulating ASML’s legacy DUV equipment. These DUV transactions evolved into a vital revenue stream. Should Chinese domestic manufacturers successfully bridge this technology gap, ASML’s existing market position in China faces direct jeopardy.
The undisclosed manufacturer reportedly built its engineering teams by recruiting specialists from competing Chinese enterprises, including the government-backed startup Shanghai Yuliangsheng Technology.
American Semiconductor Equipment Companies Join the Downturn
ASML’s decline didn’t occur in isolation. Applied Materials declined approximately 5%, Lam Research retreated nearly 7%, and KLA Corp dropped close to 5%. These corporations provide equipment for chipmaking processes adjacent to lithography — including deposition, etching, and inspection technologies.
The market rationale is straightforward: lithography technology has consistently represented the most challenging obstacle in semiconductor manufacturing. Should China overcome this barrier, market participants worry the remaining supply chain components could follow.
This sell-off coincides with Congressional momentum behind the MATCH Act, bipartisan legislation aimed at preventing China from purchasing or maintaining DUV equipment. If Chinese manufacturers can now produce these systems domestically, such restrictions may prove less effective than lawmakers anticipated.
Chinese Advancement Is Genuine — Though Nascent
Context matters significantly here. The Chinese DUV systems remain in preliminary production stages. The unidentified manufacturer intends to deliver just five machines this year, targeting up to 20 units by 2026. This volume pales compared to ASML’s production capacity.
China’s EUV technology ambitions trail even further — those sophisticated machines remain in prototype development and likely won’t reach commercial viability for years.
Nevertheless, the trajectory is unmistakable. Beijing designated lithography as a strategic national objective in 2002, and following intensified U.S. export controls in 2022, China transitioned from government-directed research toward an accelerated public-private partnership approach.
ASML’s Q2 financial report, published before Monday’s developments, had already indicated weakening Chinese demand. The company now confronts the prospect of further DUV revenue erosion in the region as domestic Chinese competitors expand production capabilities.
