CRYSCORE can offer Epi-Ready grade sapphire wafer with a very low surface roughness in complete orientation options.

C plane sapphire wafers are being extensively used for epitaxial growth of III-V and II-VI compounds, such as gallium nitride (GaN), aluminum nitride (AlN), for bright blue and green LED and laser diodes.

Different Sizes of Standard Sapphire Wafers
1 Inch C-plane(0001) Sapphire Wafers
After over 12 years extensive experience, CRYSCORE can produce high quality sapphire wafers in all orientations with unpolished and polished sides.
2 Inch C-plane(0001) Sapphire Wafers
CRYSCORE polishes the sapphire wafers by special CMP (Chemical Mechanical Polishing) technology, which is a widely used planarization technology.
3 Inch C-plane(0001) Sapphire Wafers
Sapphire is an important material used widely in the growth of III-nitride epitaxial layers (GaN, AlN, InN, AlGaN, InGaN, InAlN, etc.)
4 Inch C-plane(0001) Sapphire Wafers
Sapphire wafer is being used extensively as a substrate for III-V nitrides and for many other epitaxial films.
5 Inch C-plane(0001) Sapphire Wafers
5-inch c sapphire wafers are not as common as other specifications. However, its quality manufactured by CRYSCORE is as good as gold.
6 Inch C-plane(0001) Sapphire Wafers
Based on the continuous upgrade of sapphire technology and the rapid expansion of the application market, 4 inch and 6 inch c plane sapphire substrate wafers will be more adopted by mainstream chip companies.
8 Inch C-plane(0001) Sapphire Wafers
The 8-inch optical sapphire wafers can enable chip maker to roll out more productivity, which will help them drive down costs dramatically.
