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 $40 million in two financing rounds in 2013 and 2015 and $36 million in its Round C financing round in 2018. In 2020 Aledia announced that it plans to establish a 140 million euros LED production fab. The company raised 80 million Euros towards the new plant in 2020, and in 2022 announced a $30 million line of credit.
