Patent ID: 7518158

Claim:
A submount for a semiconductor light emitting device, comprising a semiconductor substrate having a cavity therein configured to receive the light emitting device; a first bond pad in the cavity positioned to couple a first node of a light emitting device received in the cavity to a first conductive path extending through the substrate to an external surface of the semiconductor substrate; and a second bond pad in the cavity positioned to couple a second node of the light emitting device to a second conductive path extending through the substrate to the external surface of the substrate, wherein the first conductive path and the second conductive path comprise a serially connected via connection and doped region, wherein the substrate comprises a first type dopant and the doped region of each of the first and second conductive paths comprises a second type dopant, different from the first type dopant and wherein the via connection and the doped region of each of the first and second conductive paths extend serially from the respective bond pads to the external surface of the substrate.
