    摘要: A semiconductor device comprising a semiconducting diamond layer, (e.g. single crystal or polycrystalline), a refractory metal silicide layer adjacent the diamond layer for forming a rectifying contact therewith, and an annealed interface region between the diamond layer and the refractory metal silicide layer. The annealed interface region is preferably a non-abrupt interface comprising material selected from the group consisting of silicon carbide, the carbide of the refractory metal and mixtures thereof. The present invention also provides a method for making a rectifying contact on a semiconducting diamond layer comprising the steps of forming a refractory metal silicide on the diamond layer, and annealing the refractory metal silicide and diamond layer. Preferably, the step of annealing comprises the step of heating the diamond layer and refractory metal silicide at temperature of at least about 450.degree. C.

    摘要: A rectifying contact for use at high temperatures including a monocrystalline semiconducting diamond layer on a substrate and a heteroepitaxial metal layer thereon. The metal layer has a lattice match with the diamond and is deposited on the diamond substantially in atomic registry therewith. The metal and diamond form a rectifying contact which has good mechanical adhesion and provides stable rectifying operation at elevated temperatures. The metal layer may be formed by deposition in an ultra-high vacuum. In alternate embodiments, the metal layer may be formed on a monocrystalline semiconducting diamond substrate or on at least one monocrystalline diamond area of a textured polycrystalline layer.
