8 Inch Sapphire Wafer

Sapphire is a single hexagonal crystal form of aluminum oxide(Al 2 O 3 ).It is hard,chemically inert,with thermal stability and wide light transmission range.These characteristics make it an ideal material for variety of applications such as LED and laser diode.

Sapphire wafer is widely used in semiconductor(LED,LD),Silicon On Sapphire Integrated Circuit(SOS),Radio Frequency Integrated Circuit(RFIC) etc.
