Claim:
1. A method for producing a semiconductor light emitting element comprising: providing a wafer including a semiconductor structure on or above a first main surface of a substrate; irradiating a first light-condensing position in a thickness direction of the substrate with a first laser beam from a side of a second main surface of the substrate to form an altered area in which the first light-condensing position is positioned therein and voids are formed therein, the second main surface being opposite to the first main surface; irradiating a second light-condensing position with a second laser beam, the second light condensing portion being located at a position in the altered area, the position being different from the first light-condensing position in the thickness direction of the substrate; and dividing the wafer into individual semiconductor light emitting elements.
