ASML and TSMC’s 12 Inch Photomask Initiative

ASML and TSMC’s proposed shift from 6-inch to 12-inch photomasks is an attempt to redesign a critical but often overlooked part of advanced semiconductor manufacturing. Photomasks are precision plates carrying the circuit patterns projected by a lithography scanner onto a silicon wafer. In extreme-ultraviolet lithography,… Read More
