Report: China has amassed 343 ASML immersion DUV lithography tools since 2012
The Centre for Technology & Statecraft estimates Chinese chipmakers imported 343 immersion DUV lithography scanners from ASML between 2012 and early 2026, not counting equipment sent to multinational fabs operating in China. CTS says about 270 of these are Twinscan NXT:1980i machines, which offer resolution and overlay precision that could support 7nm-class chip production through multipatterning techniques.
GoKawiil's interpretation of the reporting above, not reported fact.
CTS argues current export rules have a loophole: tools bought for older nodes can later be repurposed for more advanced ones at added cost, potentially letting Chinese fabs approach 7nm capability without EUV machines. The group's proposal to ban all immersion DUV exports and restrict parts and servicing aligns with the bipartisan MATCH Act, suggesting the report may be intended to influence that legislative push, though some of its tool-count estimates are described as questionable.
- CTS estimates China holds 343 ASML immersion DUV tools acquired since 2012.
- About 270 are said to be Twinscan NXT:1980i scanners usable for 7nm-class multipatterning.
- CTS urges banning all immersion DUV exports and servicing to China, echoing the proposed MATCH Act.
