ASML, TSMC, and Samsung Drive Industry Shift to 12-Inch Photomasks for High-NA EUV Lithography

ASML and TSMC are leading an industry initiative to transition to larger 12-inch photomasks for High Numerical Aperture (High-NA) EUV lithography, a critical step for advanced semiconductor manufacturing. Samsung has joined this effort, while Intel is already pioneering High-NA EUV in production. This shift is aimed at overcoming manufacturing constraints and enabling the production of denser, more complex chips essential for AI and high-performance computing.
