Abstract
A method for manufacturing a semiconductor light emitting device, which is capable of providing high characteristic homogeneity and reproducibility, is disclosed. The disclosed method includes forming a buffer layer over a substrate, selectively growing a nitride crystal layer on the buffer layer, forming a nitride semiconductor layer having a multilayer structure over the nitride crystal layer, forming a first electrode on the nitride semiconductor layer, attaching an auxiliary substrate to the first electrode, separating the substrate from the nitride crystal layer, forming a second electrode on the nitride crystal layer exposed in accordance with the separation of the substrate, and removing the auxiliary substrate from the first electrode.
