Abstract:
1. A method of manufacturing an integral LED component, comprising the following steps of: forming an LED epitaxial structure layer on an epitaxial wafer substrate; forming a light-reflective layer on the LED epitaxial structure layer and then forming a first bonding metal layer on the light-reflective layer; forming a second bonding metal layer on a carrier wafer; wafer bonding the first and the second bonding metal layer to form a third metal layer used as a first electrode of the LED epitaxial structure layer, so as to manufacture a composite wafer having the LED epitaxial structure layer; removing the epitaxial wafer substrate from the composite wafer, so that the third metal layer, the light-reflective layer and the LED epitaxial structure layer can be formed on the carrier wafer; forming M number of LED structure groups on the carrier wafer, wherein the M number of LED structure groups comprise N number of LED epitaxial structures, at least one third electrode and at least one fourth electrode, M and N are natural numbers greater than one, the at least one third and fourth electrode are located outside the N number of LED epitaxial structures and have opposite polarities; forming at least one second electrode on the N number of LED epitaxial structures of the M number of LED structure groups; coating a dielectric layer within a selected portion of the M number of LED structure groups; manufacturing at least one conductor material layer on the dielectric layer for electrically connecting the at least one first electrode, the at least one second electrode, the at least one third electrode, and the at least one fourth electrode with each other, so as to form a circuit; and cutting the M number of LED structure groups from the carrier wafer to separate the M LED structure groups into M number of integral LED components.
