    摘要: A low metal resistance ohmic contact alloyed to p InP material having TiW within the contact as a diffusion barrier layer between an underlay of AuZn and an overlay of Au. A process for fabricating an InP JFET containing a gate contact of respective AuZn, TiW, and Au layers and with the gate contact alloyed to p InP material of a semiconductive gate region provides an improved InP JFET having a low resistance metal alloyed ohmic contact to the gate region. Use of the TiW layer in a multilayer contact alloyed to p InP material leads to unique processing and improved InP semiconductor devices.

    摘要: A complementary metal oxide semiconductor (CMOS) device in which a single InxGa1-xSb quantum well serves as both an n-channel and a p-channel in the same device and a method for making the same. The InxGa1-xSb layer is part of a heterostructure that includes a Te-delta doped AlyGa1-ySb layer above the InxGa1-xSb layer on a portion of the structure. The portion of the structure without the Te-delta doped AlyGa1-ySb barrier layer can be fabricated into a p-FET by the use of appropriate source, gate, and drain terminals, and the portion of the structure retaining the Te-delta doped AlyGa1-ySb layer can be fabricated into an n-FET so that the structure forms a CMOS device, wherein the single InxGa1-xSb quantum well serves as the transport channel for both the n-FET portion and the p-FET portion of the heterostructure.

    摘要: Gold, which is the commonly used metallization on .beta.-silicon carbide, is known to degrade at temperatures above 450.degree. C. It also exhibits poor adhesion to silicon carbide. Schottky contacts with platinum metallization have rectifying characteristics similar to contacts with gold metallization. The platinum Schottky contacts remain stable up to 800.degree. C. Adhesion of the platinum deposited at slightly elevated temperatures is also superior to that for gold. Platinum provides a metallization that is physically more rugged and thermally more stable than conventional gold metallization.
