    摘要: An InP high electron mobility transistor (HEMT) structure in which a gate metal stack includes an additional thin layer of a refractory metal, such as molybdenum (Mo) or platinum (Pt) at a junction between the gate metal stack and a Schottky barrier layer in the HEMT structure. The refractory metal layer reduces or eliminates long-term degradation of the Schottky junction between the gate metal and the barrier layer, thereby dramatically improving long-term reliability of InP HEMTs, but without sacrifice in HEMT performance, whether used as a discrete device or in an integrated circuit.

    摘要: A method of fabricating a T-gate HEMT with a club extension comprising the steps of: providing a substrate; providing a bi-layer resist on the substrate; exposing an area of the bi-layer resist to electron beam lithography where the area corresponds to a T-gate opening; exposing an area of the bi-layer resist to electron beam lithography where the area corresponds to the shape of the club extension wherein the area corresponding to the club extension is approximately 1 micron to an ohmic source side of a T-gate and approximately 0.5 microns forward from a front of the T-gate; developing out the bi-layer resist in the exposed area that corresponds to the T-gate opening; developing out the bi-layer resist in the exposed area that corresponds to the club extension; and forming the T-gate and club extension through a metallization process.
