ASML and TSMC are backing a transition to 12-inch photomasks for High NA EUV, with a pilot line targeted for 2031 and advanced-node production using the larger format targeted for 2033. The companies announced the initiative on 8 September. ASML says the larger masks should improve High NA EUV productivity and reduce chipmaking costs, while the full release republished by GlobeNewswire sets out the timetable.
12-inch photomasks: 2031 pilot vs 2033 production
| Milestone | Target (from this announcement) |
|---|---|
| 12-inch photomask pilot line | 2031 |
| Advanced-node production readiness | 2033 |
| High NA EUV high-volume manufacturing (TSMC) | From 2030 (still on current 6-inch masks initially) |
The initiative aims to establish a 12-inch mask pilot line by 2031. The companies are targeting full lithography-system readiness for advanced-node production by 2033, although those dates describe an industry plan rather than a shipping date for consumer chips.
ASML chief executive Christophe Fouquet said the industry would first adopt High NA EUV with current 6-inch masks before moving to 12-inch masks. TSMC chairman and chief executive C.C. Wei said the collaboration is intended to lower barriers to advanced solutions at scale.
Why 12-inch photomasks matter for High NA EUV
High NA EUV production will initially continue using current 6-inch masks. ASML and TSMC say moving to 12-inch masks could increase scanner productivity, reduce chipmaking costs and remove stitching constraints. That would give advanced chipmakers more room to use High NA EUV as transistor designs become more complex.
TSMC intends to use ASML’s High NA technology in high-volume manufacturing from 2030. The companies expect the number of chip layers requiring High NA EUV to rise as advanced nodes are used for AI-focused transistor architectures.
The change is several steps upstream from the phones, graphics cards and servers that use the resulting chips. It could still affect future chip supply and manufacturing economics, including the cost and availability of AI hardware in markets such as the UAE, but no UAE pricing or rollout has been announced.
What are 12-inch photomasks?
They are a proposed larger photomask format for High NA EUV lithography, replacing the current 6-inch masks in later production stages.
When could 12-inch photomasks enter production?
ASML and TSMC are targeting a pilot line by 2031 and advanced-node production readiness by 2033.
Will this change UAE chip prices now?
No. The announcement contains no UAE pricing or rollout details; any effect on hardware economics would be longer term.
