Patent ID: 8148183

Claim:
A method for manufacturing a semiconductor light emitting device, comprising: forming a stacked body including a semiconductor layer and an insulating film on a major surface of a substrate, the semiconductor layer including a light emitting layer and separated into a plurality of elements by a separation groove, the insulating film covering the semiconductor layer and a bottom surface of the separation groove, the insulating film being more flexible and thick than the semiconductor layer; separating the substrate from the semiconductor layer by irradiating the semiconductor layer with laser light from a surface of the substrate opposite to the major surface, an edge portion of irradiation area of the laser light being positioned near an edge portion of the semiconductor layer neighboring the separation groove; and after the separating the substrate from the semiconductor layer, cutting the insulating film at the separation groove to singulate the stacked body with exposing a surface of the insulating film opposite to the bottom surface of the separation groove.
