France-based Aledia, founded in 2011, developed a technology to grow 3D GaN LEDs on 200 mm and 300 mm silicon wafers using CMOS wafer-fabrication processes and tools. Aledia says that its LED chips are 25% cheaper compared to traditional planar LED chips, and these LEDs can be used for micro-LED displays.
Aledia raised over 360 million Euro in total, with the latest 120 million Euro round announced in October 2023. In 2020 Aledia announced that it plans to establish a 140 million euros LED production fab.
The company plans to start mass producing microLEDs towards the end of 2023. Aledia is a MicroLED Industry Association member.
