China amassed 343 DUV lithography machines since 2012

Chinese chip manufacturers have imported 343 advanced immersion DUV lithography machines since 2012, according to a new report. These ArFi tools enable production of 7nm-class chips—still two generations behind the most cutting-edge tech, but a substantial capability given U.S. export controls. The purchases, mostly from Dutch supplier ASML, exclude machines installed by multinational companies operating in China.

Why it mattersAccess to large numbers of DUV tools means Chinese chipmakers can keep improving their processors despite being locked out of the most advanced chipmaking equipment. This helps China work around U.S. restrictions on semiconductor technology.
