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.

Platinum Schottky contacts remaining stable up to 800.degree. C. have been produced. The adhesion of the platinum deposited at slightly elevated temperatures is good. Platinum provides a metallization that is physically rugged and thermally stable. The Schottky contacts are made on B-Silicon carbide.
摘要:
A Schottky diode and method of making same in which a n+ doped layer, an noped layer and an undoped layer of a semi-insulating material selected from the group consisting of gallium arsenide, aluminum gallium arsenide and indium phosphide is grown consecutively on a semi-insulating substrate made of the same material. A mesa with acute angled sides is etched on the undoped layer to such a depth that the n doped layer is exposed. A Schottky and ohmic contact are then deposited on opposite sides of the mesa. The exposed n layer is then bombarded with protons at normal incidence.
