Patent ID: 7511363

Claim:
A semiconductor device assembly comprising: a semiconductor device having at least one desired surface having at least one bond pad located thereon, the at least one bond pad 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 the 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 TaN, TiN, TiW, and WN and the at least one other layer of metal comprising a silver metal alloy; and one end of a wire connected directly in contact with a portion of the copper layer base covered by the at least one layer of metal covering a portion of the copper layer base of the at least one bond pad on the at least one surface 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.
