Claim:
1. A circuit structure comprising: a III-V semiconductor compound over a substrate; a Al a gate over the AlGaN layer; a passivation film over the gate and over a portion of the AlGaN layer, wherein the passivation film includes a first opening and a second opening; a source structure including at least one conductive layer contiguously extending from over a top surface of the passivation film on a first side of the first opening to a source contact portion disposed in the first opening and to an overhead portion disposed over a top surface of the passivation film on a second side of the first opening, wherein the overhead portion is over at least a portion of the passivation film between a drain structure and the gate; the drain structure on an opposite side of the gate from the source structure and wherein the drain structure is disposed in the second opening of the passivation film; wherein a distance between the source contact portion and the gate is less than a distance between the gate and the drain structure.
