Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A nitride-based semiconductor device, comprising:
a first nitride-based semiconductor layer;
a second nitride-based semiconductor layer disposed on the first nitride-based semiconductor layer and having a bandgap greater than a bandgap of the first nitride-based semiconductor layer;
a source electrode and a drain electrode disposed above the second nitride-based semiconductor layer;
a gate electrode disposed above the second nitride-based semiconductor layer and between the source and drain electrodes; and
a single field plate disposed over the gate electrode and extending toward the drain electrode, wherein the field plate has a first end part and a second end part which are opposite each other and located at substantially the same height with respect to the second nitride-based semiconductor layer and a central part between the first and second end parts, portions of the central part are in a position lower than that of the first and second end parts, and the first end part extends laterally in a length greater than a width of the gate electrode.
