Aledia produces first micro-LED chips on 300mm silicon wafers
Aledia S.A of Echirolles, near Grenoble, France (a developer and manufacturer of 3D micro-LEDs for display applications based on its gallium nitride nanowires-on-silicon platform) has manufactured what is says are the first micro-LED chips produced on 300mm (12”) silicon wafers.
The firm, which developed its technology on 200mm (8”) silicon wafers over the past eight years, will produce the chips on both 200mm and 300mm wafers. The larger wafers provide better economic payoff and cost-effective integration with smaller-node electronics, which are only available on 300mm silicon wafers. Aledia was spun out of Grenoble-based micro/nanotechnology R&D center CEA-Leti in 2012, and the work on 300mm wafers has been performed by joint Aledia and CEA-Leti teams.
