An electroplated metal alloy including at least three elements. A multilayer interconnection structure that includes a substrate that is an interior of the interconnection structure, a conductive seed layer exterior to the substrate, and an electroplated metal alloy layer including at least three elements exterior to the conductive seed layer. A multilayer interconnection structure formed on a substrate, that includes a barrier layer, and a conductive seed layer, wherein the improvement includes an electroplated metal alloy layer including at least three elements. A method for forming a multilayer interconnection structure that includes providing a substrate, depositing a conductive seed layer, and electroplating a metal alloy layer including at least three elements exterior to the conductive seed layer.
