SAINT-GOBAIN (Lumilog) / France


Spun off from the Center of Hetero-Epitaxie Research and Applications (CHREA) of France’s National Scientific Research Center’s (CNRS) in 2001, Luminog manufactures HVPE -grown free-standing bulk gallium nitride substrates as well as MOCVD-grown 2-inch gallium nitride template epiwafers on sapphire substrates. Lumilog became a subsidiary of Saint-gobain, the world leader in construction market, design. It is expected that Lumilog enhances capital strength and gets synergy effect of Saint-gobain’s outstanding technique of polishing sapphire.
