Toshiba to start mass production of white LEDs

ntttttttttttt

Toshiba Corp will start mass production of white light-emitting diodes (LED) on a production line that the company will construct in the 200mm wafer facility at Kaga Toshiba Electronics Corporation, a production base for discrete products in northern Japan. Mass production will start from October.

The energy efficiency and long life of white LEDs is winning wide-scale application in general purpose lighting, TV backlighting, etc. and significantly boosting market size: from 700 billion yen to a projected 1 trillion yen in FY2013.

Toshiba is applying GaN-on-Silicon technology to the development of white LEDs, and has collaborated with Bridgelux Inc, a leading developer and promoter of LED lighting technologies and solutions, in white LED chip development since January 2012. The combination of Bridgelux’s crystal growth and LED chip structure and Toshiba’s advanced silicon process and manufacturing technology has succeeded in developing a prototype chip with a maximum optical output of 614mW.
