1)Material:sapphire 2)Crystal orientation:C,A,R 3)Diameter:1-180mm 4)Thickness:0.1-50mm 5)S/D:20/10 Sapphire Wafer

Worldhawk offers a series wafer with different materials. Sapphire is a material of a unique combination of physical, chemical and optical properties, which make it resistant to high temperature, thermal shock, water and sand erosion, and scratching. It is a superior window material for many IR applications from 3µm to 5µm. C-plane sapphire substrates are widely used to grow III-V and II-VI compounds such as GaN for blue LED and laser diodes, while R-plane sapphire substrates are used for the hetero-epitaxial deposition of silicon for microelectronic IC applications.
