Report: China's growing DUVi stockpile could erase US AI chip edge within a decade; ban urged
teortaxesTex · x · 2026-10-04
The Center for Technology & Statecraft (co-authored by Saif M. Khan) publishes a report urging a full China-wide ban on DUV immersion lithography exports.
Key points:
- Advanced lithography is foundational to competitive AI chips; China isn't expected to commercialize such systems at scale until the mid-2030s.
- The report models immersion scanner installs at Chinese-owned fabs and estimates six NXT:2100i systems at CXMT Anhui, carrying Zeiss's most advanced overlay manipulator — a technology of strategic weight comparable to EUV.
- At 2024–2025 import rates, China could accumulate enough lithography capacity in 5–10 years to narrow or erase the US-allied AI chipmaking advantage.
- Policy: replace partial DUVi controls with a China-wide export ban plus parts and servicing controls, securing the US advantage through 2035 and steering new fabs to the US and allies.
- The report is explicitly aimed at advancing the MATCH Act.
Commenters question what happens to the installed fleet if ASML service contracts — the mechanism protecting tool IP — are severed.
