Abstract:
A III-N device includes a III-N layer structure including a III-N channel layer, a III-N barrier layer over the III-N channel layer, and a graded III-N layer over the III-N barrier layer having a first side adjacent to the III-N barrier layer and a second side opposite the first side; a first power electrode and a second power electrode; and a gate between the first and second power electrodes, the gate being over the III-N layer structure. A composition of the graded III-N layer is graded so the bandgap of the graded III-N layer adjacent to the first side is greater than the bandgap of the graded III-N layer adjacent to the second side. A region of the graded III-N layer is (i) between the gate and the second power electrode, and (ii) electrically connected to the first power electrode and electrically isolated from the second power electrode.

Claim (Index 6):
A depletion mode transistor, comprising:\n a III-N layer structure comprising a III-N barrier layer adjacent to a III-N channel layer, a 2DEG channel in the III-N channel layer; a source electrode and a drain electrode, wherein the source electrode and drain electrode are electrically connected to the 2DEG channel; a graded III-N layer over the III-N layer structure, the graded III-N layer having a first side adjacent to the III-N layer structure and a second side opposite the first side; and a p-doped III-N layer over the graded III-N layer, the p-doped III-N layer having a third side contacting the second side of the graded III-N layer and a fourth side opposite the third side; a gate electrode directly contacting the p-doped III-N layer between the source electrode and the drain electrode; wherein a composition of the graded III-N layer is graded such that the bandgap of the graded III-N layer adjacent to the first side is greater than the bandgap of the graded III-N layer adjacent to the second side; an area of the third side of the p-doped III-N layer is less than an area of the second side of the graded III-N layer; and the graded III-N layer is electrically isolated from the source electrode and the drain electrode.
