Abstract:
In an embodiment, a wide bandgap semiconductor power device, includes a wide bandgap semiconductor substrate layer; an epitaxial semiconductor layer disposed above the wide bandgap semiconductor substrate layer; a gate dielectric layer disposed directly over a portion of the epitaxial semiconductor layer; and a gate electrode disposed directly over the gate dielectric layer. The gate electrode includes an in-situ doped semiconductor layer disposed directly over the gate dielectric layer and a metal-containing layer disposed directly over the in-situ doped semiconductor layer.
