Toshiba to start sales of white LED packages

Toshiba Corporation is to start sales of white light-emitting diode (LED) packages that offer makers of general purpose and industrial LED lighting solutions a cost-competitive alternative to current LED packages. Mass production starts this month.

Production of LED chips is typically done on 2- to 4-inch wafers with an expensive sapphire substrate. Toshiba and Bridgelux have developed a process for manufacturing gallium nitride LEDs on 200mm silicon wafers, which Toshiba has brought to a new production line at Kaga Toshiba Electronics Corporation, a discrete products manufacturing facility in northern Japan. Mass production of packages using the new line’s output starts this month.

Deployment of Toshiba and Bridgelux’s new gallium nitride-on-silicon (GaN-on-Si) technology to produce LED chips has allowed Toshiba to replace sapphire substrates and to produce the chips on a much more cost-competitive silicon substrate.

The low power consumption and long life of the white LED lighting is seeing much wider adoption in general purpose lighting, TV backlighting and other areas of application. In FY2011 the global market stood at S$8.5 billion and it is expected to almost double to $15.2 billion in FY2016.

Going forward, Toshiba will promote product development and global sales toward securing a 10% share of the world market in FY2016.
