ASML and TSMC launch initiative to transition EUV masks to 12-inch format

ASML and TSMC have announced a joint initiative to shift the semiconductor industry from 6-inch photomasks to a larger 12-inch format for High NA EUV lithography. The pilot line for these supersized masks is expected to come online by 2031, with full production readiness targeted for 2033. The current 6-inch photomask format has been the industry standard for decades. The new 6-by-12-inch format is projected to deliver roughly a 40% increase in scanner productivity. A larger mask can print more chip area in a single exposure, and the 12-inch format eliminates stitching constraints entirely, opening the door to larger, more complex chip architectures that would be impractical or impossible with current mask sizes. The High NA EUV timeline TSMC plans to incorporate High NA EUV into its advanced-node high-volume manufacturing by 2030. The new 12-inch mask format is designed specifically for these next-generation systems. Samsung has set a goal to begin High NA EUV high-volume DRAM production by 2028. Intel has already started deploying High NA EUV tools in its production processes. Both Samsung and SK Hynix have expressed support for the ASML-TSMC mask initiative. What this means for ...
