Aplane, Mplane, Rplane Sapphire Substrate
Aplane, Mplane, Rplane Sapphire Substrate

The material is grown and orientated, and substrates are fabricated and polished to an extremely smooth damage free Epi-Ready surface on one or both sides of the wafer.  A variety of wafer orientations (Cplane, Mplane, Aplane, Rplane) and sizes up to 8"(2inch to 8inch) diameter are available.

A,M,R Plane Patterned Sapphire Substrate (PSS)
A,M,R Plane Patterned Sapphire Substrate (PSS)

Patterned Sapphire Substrates (PSS) is micro-patterned sapphire substrate used to for GaN based light emitting diodes(LEDS). The PSS reduces the dislocation density in the GaN layer, enhances the light extraction efficiency and increase LEDs’brightness.
