💡ASML and TSMC Push 12-Inch Photomasks for 2031
The chip industry's next big shift: 12-inch photomasks
TL;DR
ASML and TSMC are spearheading a move to 12-inch photomasks by 2031 to lower costs and improve EUV lithography. This could boost fab productivity and reduce stitching constraints for large dies.
ASML and TSMC are leading an industry-wide push toward 12-inch photomasks, aiming to establish a pilot line by 2031. This shift could significantly lower costs and overcome limitations of high-NA EUV lithography, improving fab productivity and reducing the complexity of stitching large dies. The initiative aims to support advanced node production by 2033, with Intel Foundry and Samsung backing the move. The transition to 12-inch masks is seen as a necessary step comparable to the industry's move from 200 mm to 300 mm wafers.
Key Points
ASML and TSMC aim to establish a 12-inch mask pilot line by 2031, with supporting lithography systems ready by 2033.
High-NA EUV will initially use current 6-inch masks but moving to 12-inch masks could increase fab productivity and lower costs.
The NA in high-NA EUV stands for numerical aperture, a measure of an optical system's ability to collect and focus light.
ASML's anamorphic optics reduce the image by 4x in one axis and 8x in the other, allowing chipmakers to continue using 6-inch masks.
Large dies may require two separately exposed patterns to be stitched together, adding complexity and reducing productivity.
Why It Matters
If you're involved in semiconductor manufacturing, the move to 12-inch photomasks could significantly impact your fab's productivity and cost structure. For instance, Intel Foundry plans to enable high-NA EUV on 6-inch masks with or without stitching, while Samsung aims to introduce ASML's high-NA EUV technology into high-volume DRAM manufacturing by 2028. This transition is essential for meeting the demand for smaller, faster, and more energy-efficient chips.
