gallium nitride on silicon: vgan?, page-12

It still isn't clear dnyland whether it is their own tech involved,one that is patented by them or someone else ?

The move to a Silicon substrate will be a revolutionary step for the LED industry, and Bridgelux is well- positioned to take full advantage of the introduction of this technology. Over the past 5 years, Dr. Steve Lester, one of the industry?s pioneers in LED Research and Development, has fostered a world-class team of Bridgelux materials scientists and chip design engineers dedicated to GaN-on-Silicon R&D. Concurrently, industry-wide research and development of GaN growth on Silicon has increased rapidly. And as a result, the GaN on Silicon performance levels reported by Bridgelux today are comparable to state-of-the-art sapphire-based LEDs available 12-24 months ago. The company anticipates the delivery of its first commercially available GaN-on-Silicon products over the course of the next two to three years.

Bridgelux, which maintains an asset-light operating model, will leverage its strong R&D and Intellectual Property position in LED epitaxy to jointly manufacture silicon based LEDs. The company is currently in discussions with a number of established semiconductor companies regarding the utilization of the many fully depreciated 8-inch semiconductor fabrication operations available around the globe.

?Bridgelux?s achievement is a significant reflection of the strength of our leadership in Silicon materials and epitaxial process technology, said Bill Watkins, Bridgelux CEO. ?The significantly reduced cost-structures enabled by Silicon-based LED technology will continue to deliver dramatic reductions in the up-front capital investment required for solid state lighting. In as little as two to three years, even the most price-sensitive markets, such as commercial and office lighting, residential applications, and retrofit lamps will seamlessly and rapidly convert to solid state lighting.?
