Patent ID: 8115221

Claim:
A light-emitting device comprising: a substrate decomposition prevention layer using, as a matrix, at least one selected from the group consisting of boron nitride (B—N), silicon carbide (Si—C), and silicon carbon nitride (Si—C—N), and patterned into a predetermined shape; an n-type nitride clad layer formed on the substrate decomposition prevention layer; a nitride active layer formed on the n-type nitride clad layer; a p-type nitride clad layer formed on the nitride active layer; a p-type ohmic contact layer formed on the p-type nitride clad layer; a p-type electrode pad formed on the p-type ohmic contact layer; an n-type ohmic contact layer electrically connected to the n-type nitride clad layer by means of a patterned region of the substrate decomposition prevention layer; and an n-type electrode pad formed beneath the n-type ohmic contact layer.
