Method of making a light emitting diode array

摘要

In a light emitting diode array, an N-electrode layer (32) is extended from the bottom surface to the top surface of a semiconductor body (30) through the side surface. PN junctions (42) are exposed to the cleavage surface (S) and light is emitted therefrom. Since the N-electrode layer and P-electrode layers (41) are located on a common surface, the LED array can be mounted on a base plate through a soldering process. The LED array can be used without a self-focus lens array in an electric printer for photography.
