Classification: CPC H | IPC H

Claim 0:
1. A high electron mobility transistor (HEMT), comprising:
a first III-V compound layer;
a second III-V compound layer disposed on the first III-V compound layer, wherein a composition of the first III-V compound layer is different from a composition of the second III-V compound layer;
a third III-V compound layer disposed on the second III-V compound layer, wherein the third III-V compound layer comprises a body and a plurality of finger parts, each of the finger parts is connected to the body, all finger parts are parallel to each other and do not contact each other, and wherein the body comprises a P-type III-V compound layer and the plurality of finger parts comprise an undoped III-V compound layer;
a source electrode disposed at one side of the body and contacting the first III-V compound layer, wherein the plurality of finger parts are only disposed between the body and the source electrode and the plurality of finger parts do not contact the source electrode;
a drain electrode disposed at another side of the body and contacting the first III-V compound layer; and
a gate electrode disposed directly on the body.
