Specification :

Sapphire crystal
Sapphire crystal has excellent optical performance, mechanical property and chemical stability. It also has high strength, large hardness and high melting point. Therefore, it is widely used in fabrication of special optical element lens, missile warhead light cover and laser window. Due to particular crystal structure, high chemical stability, better heat dissipation performance, larger sizes and low prices, sapphire crystal become the key substrate material for light-emitting diode.
SiC crystal
Technological capability:
1. 2" -4" SiC wafers, including: n type SiC, semi-insulating 6H-SiC
4H-SiC
2. Surface roughness
