Based on the continuous upgrade of sapphire technology and the rapid expansion of the application market, 4 inch and 6 inch substrate wafers will be more adopted by mainstream chip companies due to their inherent advantages in production utilization.
CRYSCORE supplies a wide range of sapphire wafers either from stock or custom made to your specification for various applications. The Epi-Ready grade sapphire wafers have no particles, no cracks or pores, no scratches, or other defects. All the wafers and sapphire substrates are traceable with respect to the cassette numbers marked on the label.
