EpiValley starts 30x2 inch epiwafer production

LED maker EpiValley of South Korea says that it has qualified and begun using its Thomas Swan CRIUS Close Coupled Showerhead CCS 30x2 inch MOCVD reactor (commissioned only recently from Aixtron of Aachen, Germany) in its production facilities in Kwangju City.

EpiValley is the first company to produce high-brightness blue LED epiwafers on this system, which is claimed to be the world’s most productive MOCVD system for production of GaN-based LEDs. To date, the largest reactors for GaN-based LEDs mass production were qualified with a capacity of between 18x2 inch and 24x2 inch.

EpiValley’s plan is to manufacture LEDs for side-view application in mobile phones. “Using this system we have a big advantage with respect to quality and productivity, which allows EpiValley to compete within the huge LED BLU (back-light unit) and Llghting market,” says DJ Park, EpiValley’s president and CEO. With 12 MOCVD Systems already in operation, EpiValley claims to have the largest manufacturing capacity in Korea.
