Patent ID: 8455274

Claim:
A method for manufacturing light emitting diodes, comprising: providing a substrate; forming an upper conductive layer and a lower conductive layer on a top face and a bottom face of the substrate, respectively; forming a plurality of upper grooves and lower grooves through the upper conductive layer and the lower conductive layer in a manner that each of the upper conductive layer and the lower conductive layer is divided into a plurality of first areas and second areas alternating with the first areas; forming a plurality of cavities in the substrate through the first areas of the upper conductive layer to expose a top face of the lower conductive layer; forming a plurality of conductive posts within the substrate to electrically connect the second areas of the upper conductive layer with the second areas of the lower conductive layer, respectively; providing an overlaying layer, the overlaying layer comprising first parts covering and connecting the first areas of the upper conductive layer and the exposed top face of the lower conductive layer, respectively; fixing a plurality of light emitting chips on the first parts of the overlaying layer within the cavities and electrically connecting each of the light emitting chips with an adjacent first part of the overlaying layer and an adjacent conductive post; sealing the light emitting chips with an encapsulant; and cutting the substrate and the encapsulant to form a plurality of individual packages each comprising a corresponding light emitting chip and a corresponding post.
