The Next-Generation GaN-on-Si White LEDs

Toshiba's LETERAS white LEDs offer a cost-competitive advantage, allowing manufacturers of general purpose and industrial LED lighting to drive down costs.

High-performance white LEDs have typically been fabricated on expensive sapphire substrates in relatively small 100mm or 150mm wafer sizes. In contrast, Toshiba has developed a process that enables GaN LEDs to be produced using more cost-effective 200mm silicon wafers. This helps to reduce costs by replacing expensive sapphire substrates with more cost-competitive silicon substrates while making use of existing silicon fabrication facilities.

The low power consumption and long life of the white LED lighting is winning wide adoption in general purpose lighting, and a wide variety of applications.
