Title: Copper alloys for interconnectors and methods for making the same

Abstract

Metallic alloy interconnects (which can comprise copper) with low electrical resistivity and methods for making the same are disclosed. The electrical resistivity of thin film copper alloys was reduced by 36% with niobium solute and by 51% with iron solute compared to pure copper counterpart in dilute solute regimes (0-1.5 atomic %). The fabrication method is operated at room temperature, and does not require a high temperature annealing step.
