Aledia's nano-LED research powers forward with Veeco

Veeco's MOCVD tool will be used to grow 3D nanowire-based LEDs for lighting applications on thin silicon wafer substrates, of 8 inches or greater in diameter
CEA-Leti, a research lab based in Grenoble, France, has selected Veeco’s TurboDisc K465i MOCVD system for its program with Aledia, its nanowire-LED partner.

Aledia, a start-up company spun out of the CEA-Leti labs in 2011, is based at the CEA site.

It counts among its three founders two former CEA researchers, Xavier Hugon and Philippe Gilet.

Aledia’s goal is to manufacture 3D nanowire-based LEDs for solid-state lighting applications on thin silicon wafer substrates, of 8 inches or greater in diameter, at a cost significantly below that of conventional planar LEDs.

Nanowires are thin crystalline structures that, when electrically charged, can emit a broader spectrum of light than conventional LEDs, and can be grown on industry-standard silicon substrates.

Aledia’s nanowire technology was originally developed at CEA-Leti, and Aledia and CEA-Leti continue to develop nanowire technology in close cooperation.

Fabrice Geiger, Head of CEA-Leti’s Silicon Technology Division, comments, “We are confident that Veeco’s MOCVD system is the right equipment to help make this technology successful.”

According to Giorgio Anania, Aledia’s President and Chief Executive Officer, “The TurboDisc reactor will be an important element of our strategy to take this potentially game-changing technology towards the commercialisation phase. In partnership with CEA-Leti, we selected Veeco because our analysis indicated that at this time their MOCVD systems showed the best financial returns for 8 inch wafer production on the market.”

William J. Miller, Veeco’s Executive Vice President, adds, “We are looking forward to working with CEA-Leti and Aledia on their efforts to commercialise nanowire LED technology, which shows promise to accelerate the industry’s roadmap towards cheaper and more efficient LEDs.”
