Abstract

PURPOSE: To obtain a long-life laser by making etch pits opposing to dislocations on the rear surface of a substrate, aligning masks with a double-side mask aligning apparauts and delineating a light emission area in the position on the substrate surface side where the opposing dislocations are less.
