Abstract
A semiconductor device which includes either a single semiconductor chip bearing an integrated circuit (IC) or two or more electrically interconnected semiconductor chips, is disclosed. This device includes interconnects between device components (on the same chip and/or on different chips), at least one of which includes a region of superconducting material, e.g., a region of copper oxide superconductor having a T.sub.c greater than about 77K. Significantly, to avoid undesirable interactions, at high processing temperatures, between the superconducting material and underlying, silicon-containing material (which, among other things, results in the superconducting material reverting to its non-superconducting state), the interconnect also includes a combination of material regions which prevents such interactions.
