ASML's 6% drop on a report of Chinese immersion DUV mass production is no cause for panic. Per a Chinese semiconductor expert, the first-gen tool is five or six generations behind ASML's 1980-class machines, which Chinese fabs already stockpile, and SMEE's six dry DUV tools sold in 2023 never ran production. No Western fab is likely to qualify a Huawei-linked tool, the lost revenue was already exiting under export controls, and lithography isn't China's binding constraint. x.com x.com
