China has begun mass-producing domestic immersion DUV lithography machines through a state-owned Shanghai firm, reportedly targeting 5 units in 2026 and 20 in 2027 for SMIC, Hua Hong, and ChangXin Memory. Industry analysts remain skeptical of the breakthrough's near-term threat to ASML, citing unproven manufacturing stability and past false claims, though potential US export restrictions could accelerate Chinese self-sufficiency.

◆ ◆ The Wire takeaway
China's DUV machines aren't ready to replace ASML yet, but US export restrictions could flip that equation overnight. If you supply materials, optics, or precision components to DUV makers, the window to lock in Chinese customers before self-sufficiency is now.
