About GaN

Gallium Nitride (GaN) is widely used as substrate mainly for light-emmiting diode (blue color LED,violet color LED, ultraviolet LED and white color LED) and blue-violet color laser diode for blue ray.

Conventionally, most of GaN substrates have been made on sapphire substrate however nowadays GaN is required to meet LD and high brightness LED requirements which takes high output and durability as important factors.Product research activity on selt-reliable substrate with a nature of less occurrance of crystal defect is getting more and more active.
