Abstract
PURPOSE: To reduce a manufacturing cost for a light emitting element by a combination of a conventional technique with a diffusion process and cutting process.
CONSTITUTION: A p-type diffusion layer is provided by a Si3N4 mask 2 on a n-type CaAsP 1 to make a pn junction 3. A Al electrode 4 is provided in the center of a p- layer surface, and the substarte 1 is polished up to a thickness of 200μ about to mount a Au electrode 5. Successively, the defective elements are marked by checking the characteristics of all the elements, thereafter a dicing is perform from the surface including the full width of Si3N4 up to about two third of the full thickness. Thereafter, the dicing portion is etched to obtain a light emitting element through the separation and check to the defective elements. According to such a method, because the dicing face forms the effective light emitting surface, a great light emitting surface can be obtained. any influence due to a chip size reduction is not appeared in this processing.
