Abstract:
1. A production method for a nitride semiconductor light emitting device, the production method comprising: forming stacked layers by stacking at least an n-type semiconductor layer, a light emitting layer, and a p-type semiconductor layer on a substrate in this order; forming grooves which divide the stacked layers so as to correspond to nitride semiconductor light emitting devices to be produced; filling the grooves with a sacrifice layer; forming a metallic layer on the p-type semiconductor layer; and forming, after forming the metallic layer, a plate layer over the p-type semiconductor layer, the metallic layer, and the sacrifice layer by plating, wherein the metallic layer comprises an ohmic contact layer, a reflection layer, and an adhesion layer, formed sequentially, the adhesion layer contacts a layer formed on the adhesion layer and a layer formed under the adhesion layer, the adhesion layer contacts a top surface of the reflection layer and a peripheral portion of a top surface of the p-semiconductor layer, and the adhesion layer is made of metal.
