Patterned Sapphire Substrates (PSS) are micro-patterned wafers used to fabricate Gallium Nitride (GaN) light emitting diodes (LEDS). PSS reduces the dislocation density in the GaN layer. This results in more efficient llight extraction while increasing the brightness.

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.
