INTERCONNECT WIRES INCLUDING RELATIVELY LOW RESISTIVITY CORES

摘要

A dielectric layer and a method of forming thereof. An opening defined in a dielectric layer and a wire deposited within the opening, wherein the wire includes a core material surrounded by a jacket material, wherein the jacket material exhibits a first resistivity &rgr;1 and the core material exhibits a second resistivity &rgr;2 and &rgr;2 is less than &rgr;1.
