Claim Text:
1. A component comprising: a first metal line disposed over a substrate; an insulating layer disposed over the first metal line; a second metal line disposed over and contacting the insulating layer; a ductile metal layer disposed between the first metal line and the second metal line, wherein the insulating layer is disposed over and contacting the ductile metal layer, wherein the ductile metal layer is composed of a different metal than the first metal line and the second metal line, and wherein the ductile metal layer has a different ductility than the first metal line and the second metal line, wherein the ductile metal layer comprises undoped aluminum and the first metal line comprises copper; and a metal barrier layer disposed between the first metal line and the second metal line, wherein the metal barrier layer is disposed directly on the first metal line, wherein the ductile metal layer is disposed directly on the metal barrier layer, and wherein the insulating layer is disposed directly on the ductile metal layer, wherein the second metal line comprises a bond pad, and wherein the ductile metal layer and the metal barrier layer are only disposed in an area below the bond pad.
