Abstract: A method for manufacturing a light emitting element that includes preparing a wafer having a substrate and a semiconductor structure, the substrate including a plurality of protrusions at positions corresponding to lattice points on a triangular lattice. The method includes forming a plurality of first modified parts in the substrate by irradiating the substrate with a laser beam along first dividing lines, forming a plurality of second modified parts in the substrate by irradiating the substrate with a laser beam along second dividing lines, and dividing the wafer along the first modified parts and the second modified parts to obtain a plurality of light emitting elements.

Abstract: A method for manufacturing a light emitting element that includes preparing a wafer having a substrate and a semiconductor structure, the substrate including a plurality of protrusions at positions corresponding to lattice points on a regular triangular lattice. The method includes forming a plurality of first modified parts in the substrate by irradiating the substrate with a laser beam along first dividing lines, forming a plurality of second modified parts in the substrate by irradiating the substrate with a laser beam along second dividing lines, and dividing the wafer along the first modified parts and the second modified parts to obtain a plurality of light emitting elements.
