Abstract
A method for manufacturing a light-emitting element includes dividing a semiconductor structure into a plurality of light-emitting portions by removing a portion of the semiconductor structure so as to form an exposed region, a first surface being exposed from under the semiconductor structure in the exposed region; etching protrusions formed in the exposed region; bonding a light-transmitting body to a second surface so as to form a bonded body; forming a plurality of modified regions along the exposed region inside the substrate by irradiating a laser beam on the exposed region from the first surface side; removing a portion of the light-transmitting body that overlaps the plurality of modified regions in a plan view; and singulating the bonded body along the modified regions.
