FIELD: physics.SUBSTANCE: array of semiconductor light-emitting elements comprises: a semiconductor crystalline substrate; an insulating film lying on the surface of the substrate, wherein the insulating film is divided into two or more regions, each having two or more openings which expose the surface of the substrate; semiconductor rods stretching from the surface of the substrate upwards through the openings. Each of the semiconductor rods has a layer of an n-type semiconductor and a layer of a p-type semiconductor layered in the direction of its stretching, thus providing a p-n junction; a first electrode connected to the semiconductor crystalline substrate; and a second electrode connected to top parts of the semiconductor rods; wherein the height of the semiconductor rods, measured from the surface of the substrate, varies in each of said two or more regions.EFFECT: easy formation of a plurality of light-emitting elements which emit light beams with different wavelengths and are formed on the same substrate.15 cl, 25 dwg |
