Abstract:
1. A method for manufacturing a light emitting element, comprising steps of: preparing a wafer that has a substrate with a first main face and a second main face, in which the first main face is provided with a plurality of convex components and valleys that connect the convex components, and a semiconductor structure that is provided on the first main face; and dividing the wafer by laser scribing, in which a laser beam is emitted from the second main face side along first dividing lines and second dividing lines, to obtain a plurality of light emitting elements; wherein the convex components are in the form of pyramids, prisms, or truncated pyramids, each of which having a polyhedral bottom face with a plurality of apexes, edge lines that extend from the apexes, and side faces that link the edge lines to each other, the convex components are disposed regularly so that a plurality of bounded regions, which are regions defined by virtual boundary between side faces of adjacent convex components in the valleys, are present around the convex components, and the first dividing lines and the second dividing lines are lines that extend in a direction that intersects straight lines that link the centers of the plurality of bounded regions around a single convex component.
