1 Inch C-plane(0001) Sapphire Wafers

1 Inch C-plane(0001) Sapphire Wafers

After over 12 years of extensive experience, CRYSCORE can produce high-quality sapphire wafers in all orientations with unpolished and polished sides. The final thickness of sapphire wafers can be reduced by polishing, to get the required value, better TTV, and improved surface roughness.

Orientation offsets and flats are available upon request. For 1-inch C-plane (0001) sapphire wafers, generally, we provide no orientation flat.
