Classification: CPC H | IPC H

Claim 0:
1. A device, comprising:
a first III-V compound layer;
a second III-V compound layer over the first III-V compound layer;
a dielectric layer over the second III-V compound layer;
a source/drain contact extending through the dielectric layer to the second III-V compound layer, wherein the source/drain contact is in contact with a top surface of the dielectric layer and an inner sidewall of the dielectric layer;
a metal-containing layer over and in contact with the source/drain contact and a portion of the metal-containing layer is directly above the dielectric layer; and
a metal contact over and in contact with the metal-containing layer, wherein a bottommost surface of the metal-containing layer is wider than a bottommost surface of the metal contact and a pate field plate between a pate structure and the source/drain contact.
