SEMICONDUCTOR LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME

A method for manufacturing a semiconductor light-emitting device includes: forming a plurality of guide grooves so as to be depressed from a surface of a semiconductor structure layer toward a semiconductor substrate and to align and extend along a direction perpendicular to an extending direction of a plurality of line electrodes; forming, in each of the plurality of guide grooves, a scribe groove so as to be depressed from a bottom surface of the guide groove toward the semiconductor substrate and to extend along an extending direction of the guide groove; and dividing a semiconductor wafer along the plurality of guide grooves. The guide groove and the scribe groove are formed to have end shapes in such a manner that inner walls thereof project toward each other in the extending direction of the scribe groove.
