Chinese researchers are advancing 3nm chip production using older deep ultraviolet (DUV) lithography tools as an alternative to restricted extreme ultraviolet (EUV) machines, aiming to overcome export controls on ASML's EUV technology.

This Wire brief sits within Fusion42's coverage of Semiconductors, and 2 sources have reported it.

◆ ◆ The Wire takeaway

Your semiconductors venture must recalibrate around China's push to use older lithography tools for sub-3nm chips, signalling a shift in supply chain dependencies and competitor capabilities.
