Toshiba to start mass production of white LEDs

26 July 2012 12.00 BST

(Japan) - Toshiba is to start mass production of white LED on a production line to be constructed at their 200mm wafer facility in Kaga, Japan.

The energy efficiency and long life of white LED is winning wide-scale uptake in areas like general purpose lighting and TV backlighting, creating a significant boost in market size: from 700-billion yen (8.75-billion US dollars) 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 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. Toshiba will build on this to start mass production of white LEDs.
By advancing the establishment of white LED production in addition to power devices, a current strategic focus product area, Toshiba hopes to enhance its discrete manufacturing business.
