TSMC, ASML eye 12-inch photomasks to unlock High-NA EUV's full-field potential
What happened
Per the title, TSMC and ASML are eyeing 12-inch photomasks to unlock High-NA EUV lithography's full-field potential; this is exploratory/planned in nature, with no indication of implementation. The body provides only background: advanced semiconductor manufacturing is progressing toward 2nm and angstrom-era nodes (Å; where 1 nm equals 10 Å), bringing high-numerical-aperture extreme ultraviolet (High-NA EUV) lithography into focus. No quantities, prices, timeline, or implementation status are given in the source.
