# The U.S. Says an ASML EUV Machine May Be in China. ASML Says It's Not. Both Claims Carry Enormous Stakes. **Source:** https://glitchwire.com/news/the-us-says-an-asml-euv-machine-may-be-in-china-asml-says-its-not-both-claims-ca/ **Published:** 2026-06-21T16:33:44.371Z **Author:** Tech Desk ยท Glitchwire **Categories:** Tech, Policy ## Summary Commerce Secretary Howard Lutnick told ASML last week that Washington suspects one of its EUV lithography machines somehow ended up in Chinese hands. The allegation strikes at the foundation of the semiconductor export control regime. ## Article Commerce Secretary Howard Lutnick has delivered a warning to [ASML](https://www.asml.com/) that carries extraordinary implications for the global semiconductor industry. In meetings during April 2026, Lutnick told the Dutch chipmaker that the U.S. government believes one of its extreme ultraviolet lithography machines may have ended up in China. This would constitute a major breach of export controls that have barred ASML from selling EUV equipment to China since 2019. ASML has pushed back firmly. The company circulated a document in Washington titled "No indication of any ASML EUV system in China," counting 314 EUV machines in operation worldwide and 26 decommissioned units. None, ASML says, are in China. Senior administration officials told Bloomberg they have evidence of EUV-related components and transport equipment moving to China but have declined to produce it publicly or to ASML itself. The stakes here are significant. ASML holds a global monopoly on EUV lithography, the only technology capable of printing semiconductor patterns at nodes below 7nm. These are the chips powering everything from frontier AI models to high-performance computing infrastructure. The company's market capitalization sits near $700 billion, making it Europe's most valuable public company, a position built entirely on the irreplaceability of what it makes. ## Why This Matters EUV machines are not easy to misplace. Each weighs around 150,000 to 180,000 kilograms, costs between $150 million and $400 million depending on the generation, and requires continuous maintenance from ASML engineers to operate. ASML CEO Christophe Fouquet has stated the company tracks every machine it has shipped and walls off its China-based staff from EUV technology, documentation, and training. The commercial incentives also cut against ASML risking its export license: the company expects roughly 20% of its 2026 revenue from already-permitted sales of older deep ultraviolet tools to China. A single confirmed EUV breach would jeopardize that entire relationship. The timing of Lutnick's warning is worth noting. A bipartisan bill called the MATCH Act, introduced in April, would [go significantly further than current restrictions](/news/the-invisible-ai-tax-how-the-global-memory-crisis-is-forcing-apple-and-everyone/) by banning all DUV immersion lithography exports to China and prohibiting the servicing of machines already in the country. The bill names SMIC, Huawei, YMTC, CXMT, and Hua Hong specifically. If passed, ASML's already-declining China business would face a forced contraction. ## China's Parallel Track Whether or not an ASML machine has reached China, Beijing's domestic semiconductor program continues on a separate trajectory. Reports indicate a prototype EUV machine is undergoing testing at facilities linked to Huawei, using a laser-induced discharge plasma approach that differs from ASML's laser-produced plasma method. Western intelligence assessments put a production-capable Chinese EUV tool somewhere between 2030 and 2035. Chinese government-linked publications are more optimistic, targeting 2030. In the interim, SMIC has been producing 7nm-equivalent chips using older DUV equipment through a technique called self-aligned quadruple patterning. It works, but at significantly higher cost per wafer and lower yields than TSMC achieves with EUV. Reports suggest SMIC's cost per wafer runs 40-50% higher than TSMC's, with [yields below 50%](/news/the-3d-chip-breakthrough-that-could-keep-moores-law-on-life-support/) for 7nm production. The Chinese government covers the difference. The U.S. export control strategy has always rested on a specific assumption: that the technological chokepoint is real, that [advanced chipmaking](/news/googles-turboquant-changes-the-math-on-ai-memory-the-industry-is-still-deciding/) cannot happen without access to a small number of irreplaceable tools made by a small number of Western-aligned companies. If an EUV machine somehow did end up in China, that framework doesn't collapse overnight. But it would represent the most consequential breach of the semiconductor containment strategy that Washington has spent years constructing. Lutnick's Commerce Department has not responded to questions about whether physical evidence of an EUV system on Chinese soil exists. ASML says the claim is wrong. The government says it has evidence. [Bloomberg first reported](https://www.bloomberg.com/) the meetings. Until someone produces proof, this remains an allegation with a very large shadow. --- **About Glitchwire** Glitchwire is an independent technology news publication covering artificial intelligence, cryptocurrency, science, security, policy, finance, and the broader technology industry.
