Abstract:
1. A method for manufacturing a nitride semiconductor light emitting device comprising: forming a buffer layer on a surface of a substrate, wherein the substrate has a light transmitting property; forming a light emitting structure by sequentially stacking a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer on the buffer layer; performing mesa etching of a selective region of the second conductive semiconductor layer until the first conductive semiconductor layer is exposed; forming a first electrode on the exposed first conductive semiconductor layer and a second electrode on the second conductive semiconductor layer, respectively; lapping and polishing the substrate provided with the first electrode and second electrode formed thereon; rounding respective corners of the other surface of the substrate on which the lapping and the polishing have been completed, so as to have a designated curvature, such that the substrate has a convex lens-shaped cross-section; and dividing the substrate, the corners of which are rounded, into respective devices through scribing and breaking processes.
