From Soitec and Sumitomo: New Gallium-Nitride Tech for Solar and LED

The two companies began the joint research and development work in December 2010 and initially were able to create 2-inch wafers. They have been able to scale up to 4-inch wafers and can even do a 6-inch version. The companies are now working on setting up pilot production lines in Japan (Sumitomo) and France (Soitec) to first produce 4-inch wafers. They plan to move to the 6-inch version later, depending on customer demand. The use of gallium nitride is more common in LEDs. It also is being investigated by many developers of power conversion devices for solar and the electric grid, a large market in which silicon dominates as the material of choice for devices that adjust the current, voltage and other characteristics of electrical power. Google-backed Transphorm made its public debut last year to discuss its gallium nitride-based power conversion technology. The startup ...
