ABSTRACT:
A process is provided for making light emitting diodes by using wire segments each plated with a glossy metal. The process comprises the steps of bending each wire segment generally into a U-shape to have a pair of legs connected together by an integral connecting web, deforming the free end of one leg by transverse compression to provide a cup end, mounting a semiconductor chip in the cup end, connecting the semiconductor chip to the free end of the other leg through a wire, forming a transparent or semitransparent resin package to enclose the respective free ends of the paired legs, and cutting the connecting web off the wire segment.
