Abstract
PURPOSE: To provide the top of a light-emitting semiconductor device with a plurality of parts of high luminous intensity, by cutting the shoulder of the light-emitting top of the device along a straight line or a curve or a combination thereof at an angle of 30 to 60° to the surface of the light-emitting top.
CONSTITUTION: The shoulder of the light-emitting top of the light-emitting semiconductor device is cut at a depth of about 1000μm and the angle of 30 to 60° to the surface of the top so that the plural parts of high luminous intensity are provided on the top of the device. Light generated by the recombination of positive holes with electrons at a point A on a cross section of the device is emitted therefrom in directions 9 and 11 in the same manner as when the shoulder is not out. Since the shoulder is cut in fact, the light is emitted from the device in other directions 10 as well as in said directions 9, 11. As a result, the efficiency of the light emission is raised about twice.
