Company development
In a September 8, 2026, press release, ASML said it and Taiwan Semiconductor Manufacturing Company had formed a collaborative initiative on the transition to 12-inch photomasks for High NA extreme ultraviolet lithography. The companies established the initiative on September 7 ahead of the SPIE BACUS Conference.
The initiative targets a 12-inch mask pilot line by 2031 and aims to support the readiness of 12-inch High NA lithography systems for advanced-node production by 2033. The release said larger-format masks are expected to increase scanner productivity, lower chipmaking costs and remove stitching constraints.
TSMC said it intends to use ASMLâs High NA technology in high-volume manufacturing for advanced nodes starting in 2030. The companies described the initiative as an industry collaboration involving semiconductor manufacturers, mask suppliers and other ecosystem partners.
