Patent ID: 7939349

Claim:
A method of manufacturing a nitride-based semiconductor light-emitting device comprising: providing a support substrate, a reflective layer, a p-type nitride-based semiconductor layer, a light-emitting layer, an n-type nitride-based semiconductor layer and an n-type In a Ga 1-a N (0≦a≦1) layer layered in this order, wherein the light-emitting layer, the n-type nitride-based semiconductor layer and the n-type In a Ga 1-a N (0≦a≦1) layer are formed using a growth substrate; forming irregularities on a light extraction surface on an upper surface of said n-type In a Ga 1-a N(0≦a≦1) layer by removing the growth substrate; and providing an n-type electrode on the upper surface of the n-type In a Ga 1-a N (0≦a≦1) layer; wherein, the reflective layer is in ohmic contact with the p-type nitride-based semiconductor layer and functions as a p-type-use electrode; and the p-type use electrode is a layer or a stack selected from a group consisting of a Pd layer, an Ag layer, a stack of a Pd layer and an Au layer, a stack of an Ag layer and an Au layer, and a stack of a Pd layer, an Ag layer and an Au layer.
