12 inch sapphire wafers of optical grade are used by researchers for fluid handling. The larger diameter and thickness provide the researcher with a strong substrate to experiment on resulting in greater yield.
300mm (12 inch) sapphire is now largest wafer for Light Emitting Diodes (LEDs) and consumer electronics.
For the first time, higher yields can be obtained from the 300mm Al2O3 wafer thus increasing production yield while reducing production costs.
Unlike other 300mm sapphire producers, UniversityWafer, Inc. and our partners will sell as few as one wafer.
