Japan-based semiconductor material provider Dai Nippon Printing (DNP) will supply Rapidus with the photomasks for 2nm chips after mass production
According to DNP's press release and Nikkei
following the development of photomasks that support 3nm logical chips made by EUV lithography in 2023
the company will begin full-scale development of a photomask for 2nm logic chips that support EUV lithography in fiscal 2024 (April 2024 to March 2025) and plans to invest JPY50 billion (US$330 million) to bring online its second and third Multi-Beam Mask Writing (MBMW) tools for 2nm generation EUV lithography after introducing its first MBMW machine in 2016
DNP expects to complete the development of a photomask for 2nm generation by fiscal 2025 and begin mass production of the material in Kamifukuoka
a Belgium-based microelectronics research center
to develop photomasks for the next generation of EUV processes
is collaborating with IBM in the US to develop photomasks for use in 2nm chip processes
The goal is to commence mass production by 2026
Major chipmakers like TSMC and Samsung Electronics make photomasks or pellicles for 3nm and 5nm chips without sourcing them from other material suppliers
Excluding in-house photomask production mentioned above
the market is controlled by Japan-based DNP
The expansion in investment announced by DNP in photomask for advanced chips indicates the clustering of suppliers in the chip ecosystem in Japan following Rapidus' foray into developing and manufacturing 2nm logical chips
