Patent ID: 8124997

Claim:
A nitride semiconductor light emitting device comprising: a conductive substrate; a light emitting structure comprising a second conductivity nitride layer, an active layer and a first conductivity type nitride layer sequentially formed on the conductive substrate; an electrode formed on one portion of the first conductivity type nitride layer; and a light scattering layer formed on the other portion of the first conductivity type nitride layer, the light scattering layer formed of a material selected from a group consisting of sapphire, SiC, MgAl 2 O 4 , MgO, LiAlO 2 and LiGaO 2 and having an upper surface in which uneven surface structures are formed, wherein ions having a larger radius than that of a particle of the material forming the light scattering layer are injected into the light scattering layer in order to destroy the crystallinity thereof.
