ASML and TSMC target a 12-inch photomask pilot line by 2031
The initiative seeks a larger mask format for High NA EUV lithography
Event / data period: 2026-09-07
Published: · Updated:

ASML and TSMC said they formed an industry initiative on 7 September to support a transition to 12-inch photomasks. The semiconductor industry has long relied on 6-inch masks; the partners say a larger format could support the use of High NA EUV lithography.
The companies target a 12-inch mask pilot line by 2031 and readiness of lithography systems for advanced-node production by 2033. These are industry-wide partner targets, not a Dutch production line or completed capacity.
