Advanced Lithography Equipment to Transform Samsung’s Fine
Samsung Electronics is collaborating with ASML to develop 12-inch photomasks for advanced semiconductor manufacturing, aiming to improve productivity and reduce costs. The new masks will support High-NA EUV lithography systems for ultra-fine processes, with Samsung planning to be the first to use them in mass DRAM production by 2028. The shift from 6-inch masks is driven by the increasing complexity of AI semiconductor circuits.
