The US says ASML’s top chip tool may be in China. ASML says it isn’t

Does that have anything to do with why Lutnick is suddenly pressing ASML on EUV? Nothing public connects the two. It could be entirely unrelated. But a federal official scrutinizing a monopoly while his own agency has money riding on a startup angling to improve that monopoly’s core technology is worth examining.

xLight isn’t the only outside bet on the future of lithography. Peter Thiel — who has his own long-running ties to Trump’s political orbit — has backed Substrate, a separate startup explicitly pursuing its own EUV-rival technology, with ambitions to compete with ASML more directly than xLight says it intends to.

As Bloomberg notes, a bipartisan bill moving through Congress would go much further than EUV — it calls for an effective ban on all of ASML’s deep ultraviolet (DUV) shipments to China, the less advanced lithography tools that account for roughly a fifth of the company’s expected 2026 revenue. The bill cleared a key committee in April, and the Trump administration hasn’t taken a formal position on it.
