Abstract
A semiconductor light emission device is disclosed. The semiconductor light emission device includes: a substrate; a current concentration preventing pattern formed in a mesh net shape on the substrate; an n-type clad layer formed on the substrate loaded with the current concentration preventing pattern; an active layer and a p-type clad layer sequentially formed on the n-type clad layer; an n-type electrode formed on a part of the n-type clad layer which is exposed by partially etching the p-type clad layer and active layer; and a p-type electrode formed on the p-type clad layer. The current concentration preventing pattern is formed in a double layer structure which includes a first layer formed from one material of SiO and SiN and on the substrate, and a second layer formed from a metal material and on the first layer.
