Patterned Sapphire Substrates

We, along with our partners, can fullfill all your PSS needs.

Using Patterned Sapphire Substrates can significantly increase the light output of LEDs. Benefits include:

- Increased light emissions of active quantum well layers as the result of reduced epitaxial defect density.

-PSS reduces light loss due to the Total Internal Reflection (TIR) phenomena by enabling a photon scattering effect.

Below is just an example of PSS that we sell.

2" PSS with the following pattern specifications:

Pattern Pitch 3.0um ± 0.15um
Pattern Bottom 2.7um ± 0.15um
Pattern Space 0.3um ± 0.15um
Pattern Height 1.7um ± 0.15um
