2 Inch C-plane(0001) Sapphire Wafers

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, and provides the customers with high surface quality sapphire wafers at low cost.


We carry a variety of standard sapphire wafers and sapphire substrates in stock to ensure a quick delivery. The wafers are cleaned in class 100 cleanroom by ultrapure water with quality above 18 MΩ *cm, and then packed in clean cassettes. 25 pcs a pack or single pack is available to maximize customer flexibility in their research.
