Patent ID: 7572657

Claim:
A method for the fabrication of a semiconductor light-emitting device, comprising the steps of: stacking at least a first conductive type semiconductor layer, an active layer and a second conductive type semiconductor layer on a substrate to form a wafer; forming on a side of growth surfaces of the semiconductor layers first trenches so as to expose a lateral surface of the first conductive type semiconductor layer at the end of the first trench forming step; forming second trenches reaching the substrate from above the first trenches by the use of a laser beam so that at least a part of the lateral surface of the first conductive type semiconductor layer remains exposed at the end of the second trench forming step; forming third trenches from the substrate at positions corresponding to the second trenches by the use of a laser beam; using a dicing blade to correct a shape of the third trenches; and dividing the wafer into chips.
