Gallium Nitride is one kind of wide-gap compound semiconductors. Gallium Nitride (GaN) substrate is
a high-quality single-crystal substrate. It is made with original HVPE method and wafer processing technology, which has been originally developed for 10+years in China. The features are high crystalline, good uniformity, and superior surface quality. GaN substrates are used for many kinds of applications, for white LED and LD(violet, blue and green) Furthermore, development has progressed for power and high frequency electronic device applications.
