ABSTRACT:
Disclosed herein are a flip chip type nitride semiconductor light emitting device, which comprises a substrate for growing a nitride semiconductor material, an n-type nitride semiconductor layer formed on the substrate, an active layer formed on at least a part of the n-type nitride semiconductor layer, a p-type nitride semiconductor layer formed on the active layer, a bonding force providing layer formed on the p-type nitride semiconductor layer and adapted to provide a bonding force relative to the p-type nitride semiconductor layer, a reflective electrode layer formed on the bonding force providing layer, and adapted to reflect light produced in the active layer toward the substrate and to diffuse electric current, and a cap layer formed on the reflective electrode layer, and adapted to provide a bonding force between the reflective electrode layer and a bonding metal and to reduce contact resistance.
