Patent ID: 8304660

Claim:
A fully reflective and highly thermoconductive electronic module, comprising: a metal bottom layer having a first reflective surface; a transparent ceramic layer having an upper surface and a lower surface, wherein the lower surface of the transparent ceramic layer is bonded to the first reflective surface of the metal bottom layer; and a patterned metal wiring layer disposed on the upper surface of the transparent ceramic layer, wherein the first reflective surface reflects a first light ray, transmitting through the transparent ceramic layer, to the upper surface of the transparent ceramic layer, the metal wiring layer has a second reflective surface, the second reflective surface is disposed opposite the first reflective surface the first reflective surface reflects a second light ray, transmitting through the transparent ceramic layer, to the second reflective surface, and the second reflective surface reflects the second light ray to the first reflective surface, which finally reflects the second light ray to transmit through the transparent ceramic layer.
