Claim 11:
12. The method of claim 11 further comprising:
forming a source metal contact layer on each of the plurality of fins fabricated in the first portion of the second epitaxial semiconductor layer;
forming a gate metal contact layer on the first portion of the third epitaxial semiconductor layer;
forming a dielectric layer on the source metal contact layer, the gate layer, the gate metal contact layer, the isolation region, the anode metal layer, and the body diode region;
forming a photomask on the dielectric layer to define through-hole locations;
etching the dielectric layer to form through-holes terminating on the source metal contact layer, the gate metal contact layer, and the anode metal layer;
removing the photomask;
filling the through-holes with a conductive metal layer;
forming a source metal layer; and
forming a drain layer.
