Patent ID: 8378380

Claim:
A nitride semiconductor light-emitting device comprising: a light-emitting device chip including a first electrode and a second electrode; and a reflection layer on both lateral sides of the light-emitting device chip, the reflection layer comprising a first reflection layer on a first lateral side of the light-emitting device chip and a second reflection on a second lateral side of the light-emitting device chip, wherein the reflection layer reflects a portion of light generated from the light-emitting device chip to the top side of the light-emitting device chip, wherein the light is emitted through the top side of the light-emitting device chip, wherein the reflection layer is in contact with the both lateral sides of the light-emitting device chip, and wherein a top surface of the first reflection layer is adjacent to the first electrode, a top surface of the second reflection layer is adjacent to the second electrode, and the top surface of the first reflection layer is lower than the top surface of the second reflection layer, wherein the reflection layer comprises an Al x In y GaN layer (0≦x≦1, 0≦y≦1) and a GaN layer, and wherein a lower-most surface of the first reflection layer and a lower-most surface of the second reflection layer are at a same level with a bottom surface of the light-emitting device chip.
