Post reports China’s first domestically produced DUV lithography machines being delivered to SMIC, Hua Hong, and CXMT this year.
Author’s thesis: if China scales production, global chip stocks will be “cooked” – a bearish call on the semiconductor sector.

July 27 (Reuters) - China has begun manufacturing domestically (DUV) lithography machines, The Information reported on Monday.
The machines are expected to be delivered this year to leading Chinese chipmakers, including Semiconductor Manufacturing International Corp, opens new tab, Hua Hong Semiconductor opens new tab and ChangXin Memory Technologies.
Chip stocks dropped after the report.

Chip stocks about get cooked if they scale the production
China is manufacturing DUV lithography tools domestically, targeting delivery to leading Chinese foundries. If scaled, this reduces reliance on ASML imports and could boost Chinese chipmaking capacity, pressuring global semiconductor margins and pricing. A long‑term structural headwind, but near‑term impact is negligible given tiny production volumes. Production is only 5 units in 2026 and 20 in 2027; technology is immersion DUV (two generations old); China has a history of overhyped tech breakthroughs.
China’s domestic DUV machines could eventually reduce ASML’s DUV sales to China, a key revenue stream. Export restrictions already limit ASML; self‑sufficiency in older DUV further curbs future orders. Negative for ASML’s China exposure, though immediate revenue impact is minimal. ASML’s EUV and High‑NA EUV monopoly remains unchallenged; China already had access to DUV via ASML; production numbers are trivial.
