Abstract
Circuit assemblies are disclosed which include a supporting substrate, a plurality of conductive lines supported on the substrate and a deposited phase-change material capable of an energy induced phase change from an initially high resistance state to a relatively low resistance state placed in electrical contact with the conductive lines. The assemblies also include contact receiving means connected to the conductive lines at preselected discrete locations to receive externally applied contact means, such as electric probes, for applying voltages across selected portions of the conductive lines. The application of such voltages can induce a phase change in portions of the phase-change material which bridge breaks in the conductive lines of such circuit subassemblies, changing such portions from their high resistance state to their low resistance state, thereby forming electrically shunting conductive paths around such open circuits. There are also disclosed methods of making such circuit assemblies.
