Future TechnologyThe US Government Thinks ASML's Most Advanced Chip Tool Is Inside China
Key takeaways
- The US government claims one of ASML's top EUV lithography machines may be inside China
- ASML denies the claim and says its tools have not been shipped to China
- High-NA EUV machines cost around 350 million dollars each and require strict export approvals from both the Netherlands and the US
- ASML has previously deactivated machines remotely to enforce export compliance
The US government has raised the alarm that one of ASML's most powerful extreme ultraviolet lithography machines, the kind that's essential for manufacturing the world's most advanced chips, may have found its way into China. ASML, for its part, says it hasn't happened.
ASML's high-NA EUV tools are the single most export-controlled items in the semiconductor world. The Netherlands-based company needs both Dutch and US government approval to export them, and China has been firmly off the approved list. Each machine costs around 350 million dollars and there are only a handful in existence globally, so this isn't the kind of equipment that goes missing quietly.
ASML has a strong commercial reason to comply: losing its export licences would be catastrophic for a business that supplies every major chipmaker on the planet. The company has previously been meticulous about compliance, deactivating machines remotely when required and maintaining detailed logs of tool locations.
What's genuinely unclear is where the US claim is coming from and what evidence backs it. If a machine did end up in China, the more interesting question is how, given the weight, complexity, and service requirements of these tools. They need regular on-site maintenance from ASML engineers, which makes concealing one extraordinarily difficult. This dispute is worth watching closely as US-China semiconductor tensions continue to escalate.
