Claim Text:
1. A semiconductor structure comprising: a substrate of a first material type, the substrate having a first surface and a second surface; a first semiconductor region comprising a Group III-nitride material on the first surface of the substrate and including a first fin structure, the first fin structure comprising: a generally horizontal first top surface; a recessed surface portion adjacent the first top surface; and first sidewall surfaces extending between the recessed surface portion and the first top surface, the first sidewall surfaces being sloped so that a base portion of the first fin structure is wider than the first top surface; a second semiconductor region comprising a Group III-nitride material disposed over the first fin structure; a gate conductor overlying at least part of the recessed surface portion; a first current carrying electrode electrically coupled to the second semiconductor region along at least the first top surface; and a shield conductor above and insulated from the gate conductor.
