Abstract
A method for manufacturing a light-emitting element includes: forming a semiconductor structure comprising a light-emitting layer on a first surface of a substrate, wherein the first surface comprising a plurality of protrusions and a second region; dividing the semiconductor structure into a plurality of light-emitting portions by removing a portion of the semiconductor structure so as to form an exposed region of the substrate, wherein the second region is exposed from under the semiconductor structure in the exposed region; bonding a light-transmitting body to a second surface of the substrate that is opposite the first surface so as to form a bonded body, wherein the light-transmitting body comprises a fluorescer; forming a plurality of modified regions along the exposed region; 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.
