flag China's SMIC tests homegrown deep UV lithography machine for 7nm chips, aiming to cut reliance on U.S. and Dutch tech.

flag China's SMIC is testing its first domestically built deep ultraviolet lithography machine, developed by Shanghai startup Yuliangsheng, marking progress toward self-reliance in semiconductor manufacturing. flag The machine aims to support 7nm production and potentially scale to 5nm, though yield rates remain low due to alignment challenges. flag This effort, driven by rising domestic demand from AI firms and government push for in-house tech, seeks to reduce dependence on foreign equipment, particularly from ASML, amid ongoing U.S. export restrictions.
