Claim:
1. A semiconductor device comprising: a substrate; a source region over the substrate; a guard ring over the substrate, the guard ring being separated from the source region by a first spacing; a first heat conductive layer over and coupling the source region and the guard ring; a first via over a first portion of the first heat conductive layer; a second via separate from the first via over a second portion of the first conductive layer; a second heat conductive layer over and coupling the first via and the second via; a third via over the first heat conductive layer; and a third heat conductive layer coupled to the third via, wherein the third heat conductive layer is level with the second heat conductive layer, and the third heat conductive layer is separated from the second heat conductive layer, wherein the first heat conductive layer is configured to dissipate heat generated by the semiconductor device from the source region to the guard ring and the substrate.
