摘要： A method of forming bond pads includes providing a substrate including an integrated circuit (IC) device formed thereon having an oxidizable uppermost metal interconnect layer which provides a plurality of bond pads that are coupled to circuit nodes on the IC device. The plurality of bond pads includes a metal bond pad area. A cobalt including connection layer is deposited directly on the metal bond pad area. The cobalt including connection layer is patterned to provide a cobalt bond pad surface for the plurality of bond pads, and a solder material is formed on the cobalt bond pad surface.
