A new FT excerpt says DUV specs, not price, decide whether China’s tools can ship

The post is a reaction to a Financial Times excerpt about lithography and China’s chip-making constraints. The quoted text argues that DUV tool specs, matched machine overlay, and yield requirements—not just price—determine whether a tool is usable in a fab, and says Chinese fabs still rely on ASML DUV machines bought before export controls or sourced second-hand. The attached FT screenshot also mentions SMIC testing a Chinese-made 28nm DUV tool for 7nm production.
