China produces photonic chip wafers without ASML equipment, cutting costs to one tenth
China\'s semiconductor equipment company Prinano (PRINANO) said it has succeeded in making photonic chip wafers without ASML\'s deep ultraviolet lithography tools, using its own nanoimprint lithography technology. The company said it produced 8-inch wafers and could cut manufacturing costs to about one-tenth of conventional methods. The announcement draws attention as export controls restrict China\'s access to advanced lithography equipment, though some analysts urged caution due to undisclosed yield, throughput and mass-production timelines.
