Aledia, a developer and manufacturer of next-generation 3D LEDs for display applications, has announced its intention to build a production site in Champagnier, in the Grenoble metropolitan area. The plan is to start production by 2022. In the global battle between LED manufacturers to lower costs and increase light output, France has long been absent. Aledia expects to change the situation as it claims its WireLED technology divides the price of lumen by ten while improving the lighting efficiency. Late 2019, Aledia invested €20 million in a R&D 4,000-square-meter facility in Échirolles, near Grenoble, to speed up R&D and rapidly align its products with customer specifications. Today, the startup takes another step towards mass production with the creation of a 52,000-square-meter LED production site, according to Invest in Grenoble Alpes. It expects to create 550 new jobs within 4 years, with an initial investment of €140 million.

Spun out of the CEA-Leti labs in 2011, Aledia develops and manufactures LEDs based on a 3D architecture using gallium-nitride-on-silicon (GaN-on-Si) nanowires. Aledia’s LEDs are manufactured on 8-inch (200mm) standard silicon substrates and scalable to 12-inch (300mm) silicon substrates while most LED manufacturers use 6-inch sapphire substrates. This significantly lowers the company’s production costs. Aledia claims its 3D LED technology enables high brightness (x1000 of today’s average screen), high-resolution, low-power and cost-effective displays, all of which are key parameters in a variety of existing and future mobile display applications including laptops, tablets, mobile phones, augmented/virtual reality (AR/VR) and smart watches. Aledia’s WireLED technology is based on eight Leti patents. In December 2019, Aledia and TowerJazz announced a process development partnership to bring Aledia’s nanowire-LED technology into commercialized volume production. This development is based on Aledia’s IP and uses TowerJazz’s Transfer Optimization and Development Process Services (TOPS). To support its activities and projects, Aledia raised over €38.4 million in two financing rounds in 2012 and 2015 and €30 million in a Round C financing round in 2018 with Intel Capital as a new investor. It was also one of the 123 high-potential startups to be selected as part of La French Tech 120 program and to benefit from a dedicated accelerated scheme.
