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.

Naver Cloud said on Wednesday it held a seminar on sovereign AI-based defence AX development strategies and unveiled an AI approach applicable to the battlefield. An executive presented an omnimodal AI model that integrates text, voice, video and maps, and proposed forward-deployed engineers as a core element of defence AI sovereignty. The company also outlined a defence-only AI data centre architecture and a plan to link dispersed military data into an ontology-based knowledge system.
