Claim:
1. A semiconductor device comprising: a nitride semiconductor layer; a gate electrode located over the nitride semiconductor layer, and extending along a first axis in plan view; an interlayer insulating film located over the gate electrode and the nitride semiconductor layer; a source pad located over the interlayer insulating film, and extending along a second axis which is perpendicular to the first axis in plan view; a drain pad located over the interlayer insulating film, and extending along the second axis in plan view, the drain pad being spaced from the source pad; a source electrode extending longitudinally along the first axis toward the drain pad in plan view, and connected to the source pad; and a drain electrode extending longitudinally along the first axis toward the source pad in plan view, and connected to the drain pad, wherein the interlayer insulating film has a first recessed portion and a second recessed portion extending longitudinally along the first axis in plan view, wherein the first recessed portion longitudinally extends in the source electrode and the source pad in plan view, wherein the source electrode and a part of the source pad are connected to the nitride semiconductor layer through the first recessed portion.
