Dai Nippon Printing to mass produce photomasks for Rapidus chip

TOKYO -- Dai Nippon Printing will begin mass producing photomasks, used in printing semiconductor circuits, in Japan in fiscal 2027 for Rapidus, which aims to produce cutting-edge semiconductors domestically.

The company will invest an estimated 50 billion yen ($330.3 million) to develop and mass-produce photomasks for 2-nanometer products. Photomasks are plates that let light shine through and bake circuits onto the silicon wafers that act as semiconductor substrates.
