Patent ID: 7489041

Claim:
A semiconductor device assembly comprising: a semiconductor device having surfaces having a desired configuration of bond pads thereon, the desired configuration of bond pads located on a surface of the semiconductor device, and active circuitry connected to the desired configuration of bond pads, each bond pad of the desired configuration of bond pads located on the surfaces of the semiconductor device connected to the active circuitry including: a copper layer base; and at least two layers of metal, one layer comprising at least one layer of metal covering a portion of the copper layer base of at least one bond pad and at least one other layer of metal covering a portion of the at least one layer of metal, the at least one layer of metal comprising a nickel metal and the at least one other layer of metal comprising a silver metal; and one end of a wire directly connected without an intervening layer of the at least two layers of metal therebetween to a portion of the copper layer base of the at least one bond pad through a portion of the at least one other layer of metal on the at least one layer of metal on at least a portion of the copper layer base.
