Patent ID: 7674643

Claim:
A method of manufacturing a GaN semiconductor light emitting device comprising the steps of: a) preparing a substrate for growing a GaN semiconductor material; b) forming an n-type GaN clad layer doped with Al on the substrate; c) forming an active layer having a quantum well structure on the n-type GaN clad layer; and d) forming a p-type GaN clad layer on the active layer, the method further comprising the step of: e) forming a buffer layer on the substrate before the step b); f) removing a predetermined portion of the active layer and p-type clad layer to expose a predetermined portion of the n-type clad layer; g) forming a p-metal layer on the p-type clad layer; and h) forming a p-side bonding electrode and an n-side electrode on the p-metal layer and on the exposed portion of the n-type clad GaN layer, respectively; wherein in step b) the n-type GaN clad layer is doped with Al in a content of 0.01% to 1%.
