PATTERNED SAPPHIRE SUBSTRATES

Sapphire wafer is the most widely used substrate material in semiconductor lighting industry, and pattern sapphire substrate(PSS) is the general method to improve the luminous efficiency of semiconductor lighting devices. These sapphire substrates are with periodic structures of various shapes such as cone, dome, pyramid, and pillar, etc.

Cryscore's Excellent Patterned Sapphire Substrates

Pattern dimension, aspect ratio, and uniformity across the wafer as well as consistency from wafer to wafer, are important factors to improve the light extraction. Currently, we provide 2-inch and 4-inch patterned optical sapphiresubstrates (pss waferand pss sapphire) with the following specifications. Diameter: 2.7 +/- 0.1 μm. Spacing: 0.3 +/- 0.1 μm. Depth: 1.7 +/- 0.15 μm.
