DNP Develops Photomask Process for 3nm EUV Lithography | DNP Group
DNP announced a photomask process compatible with 3nm EUV lithography, extending its prior 5nm EUV capability. The development is a supply‑chain readiness milestone that could increase demand and complexity for photomasks and process control as advanced-node logic and memory ramps continue.
Linked assets
Key tickers tied to this development include DNP Group (7912.T) and industry peers/beneficiaries such as KLAC (inspection/process control), ASML (ASML), TSMC (TSM) and rival mask maker (7911.T). Outcomes depend on DNP converting capability into commercial supply and on broader EUV adoption.
Dai Nippon Printing Co., Ltd. — developer of the announced 3nm EUV-compatible photomask process.
Direct beneficiary if DNP converts capability into commercial supply; higher mask complexity/value at 3nm EUV.
KLA Corporation — inspection and process-control equipment supplier.
Process control intensity rises with EUV and tighter CDs; mask/wafer inspection tailwinds.
ASML Holding N.V.
EUV adoption breadth underpins long-cycle demand, though this announcement is indirect.
TSMC — leading advanced-node foundry critical to 3nm production ramps.
3nm product supply/ramps rely on EUV-ready masks; positive as a de-risking signal, but already largely priced into TSM narrative.
Rival mask maker (ticker 7911.T).
Potential competitive share loss in merchant EUV masks if DNP’s process proves superior; evidence still limited.

Dai Nippon Printing reports a new photomask manufacturing process compatible with 3nm EUV lithography. The announcement updates DNP’s prior 5nm EUV capability and is presented as positioning DNP to meet increased EUV mask demand tied to advanced-node logic and EUV use in memory.
Dai Nippon Printing (DNP) says it developed a photomask manufacturing process compatible with 3nm EUV lithography, extending prior 5nm EUV capability and positioning itself for increased EUV mask demand as advanced-node logic (smartphones, data centers) and EUV in memory expand. This is a positive, but second-order, supply-chain milestone (mask readiness), most actionable for semiconductor capital equipment and mask/reticle ecosystem beneficiaries rather than broad-market timing.
