Patent ID: 7592246

Claim:
A method of forming a portion of a bond pad for a semiconductor device assembly having a semiconductor device and having a substrate having an upper surface and a lower surface, the method comprising: forming a layer of insulating material on the substrate; forming a separate passivation layer over the insulating material on the substrate; depositing a layer of copper on a portion of one of the upper surface and the lower surface of the substrate in contact therewith for forming a plurality of circuits of the semiconductor device, at least one circuit terminating in a bond pad of copper formed from the layer of copper; depositing at least one layer of metal on at least a portion of the layer of copper for forming at least one bond pad having at least one layer of metal thereon on one surface of one of the upper surface and the lower surface of the substrate, the at least one layer of metal comprises at least a layer of one of silver metal, a silver alloy metal, a gold alloy metal, a silver and gold alloy metal, and a noble metal alloy; forming a ball from wire; and consuming a portion of the at least one layer of metal using the ball formed from wire when forming a connection to the layer of copper through a portion of the at least one layer of metal on at least a portion of the layer of copper.
