ABSTRACT:
Light emitting p-n junction diode elements in the form of small spheres having an outer layer of semiconductor material of one conductivity type and a subsurface layer of semiconductor material of an opposite conductivity type are mounted to one surface of an insulating substrate member in holes of a proper size to allow a portion of each diode element to protrude past the other surface of the substrate; metallic coatings on one surface of the substrate provide electrical contacts to the outer layers of the spheres and metallic coatings on the other surface of the substrate provide electrical contact to the subsurface semiconductor layer of the spheres in an area where the surface layer has been removed.
