Abstract
A method of manufacturing a light emitting element includes: providing a wafer including: a substrate, and a semiconductor structure; irradiating the substrate with a laser beam to form a plurality of modified regions in the substrate; and subsequently, separating the wafer into a plurality of light emitting elements. Irradiating the substrate with a laser beam includes: performing a first irradiation step comprising irradiating the laser beam along a plurality of first lines that extend in a first direction that is parallel to the first face and that are aligned in a second direction that is parallel to the first face and intersects the first direction, and subsequent to performing the first irradiation step, performing a second irradiation step comprising irradiating the laser beam along second lines that extend in the second direction.
