Abstract:
1. A method of manufacturing a light-emitting structure, comprising: providing a substrate; forming a semiconductor multilayer on the substrate, the semiconductor multilayer comprising a p-type semiconductor layer, an n-type semiconductor layer, and a light-emitting region between the p-type semiconductor layer and the n-type semiconductor layer, wherein the p-type semiconductor layer or the n-type semiconductor layer has a varying impurity concentration therein; forming a pre-covering layer on only a portion of the p-type semiconductor layer and the n-type semiconductor layer; forming an insulating layer on the p-type semiconductor layer and the n-type semiconductor layer and exposing a part of the pre-covering layer; and electroless plating an electrode layer by immersing the exposed pre-covering layer into an electrolyte having metal ions which reduce and deposit the electrode layer on the exposed pre-covering layer; wherein the pre-covering layer is a seed layer for electroless plating the electrode layer.
