LED component by integrating epitaxial structure and package substrate together and method of manufacturing the same

摘要

The present invention discloses an integral LED component which integrates LED epitaxial structures electrodes and interconnect with a package substrate together and an integral manufacturing process thereof. The integral LED component can be made with multiple epitaxial structures or with just a single epitaxial structure. The integral LED component can be mounted into a hollow carrier. And by having support by the hollow carrier, the package substrate can be mounted and contacted with a heat conductive or a dissipation device. The integral LED component is fabricated by wafer level process and cut from the wafer as an independent component. By different manufacturing process, the integral LED component can be made as Vertical LED structure or Lateral LED structure.
