ABSTRACT:
An electrically conductive material coated with a plurality of layers, includes a metal or metal alloy substrate; a barrier layer deposited on said substrate effective to inhibit diffusion of constituents of said substrate to said plurality of layers; a sacrificial layer deposited on said barrier layer effective to form intermetallic compounds with tin; a low resistivity oxide metal layer deposited on said sacrificial layer; and an outermost layer of tin or a tin-base alloy directly deposited on said low resistivity oxide metal layer.
