China Sapphire Wafers

Product Description:
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.

Features:

All orientations are available, custom orientation is welcome Wafer size from 2 to 6 inches are available for all typesThin wafer down to 250um for 2 inch, 300um for 4 inch and 300um for 6 inch
