摘要: Tin-based wirebond structures and wirebonds formed thereon. In some embodiments, an electronic package includes a semiconductor die located over a substrate and a wire configured to couple a terminal of the semiconductor die to a bond pad on the substrate. A wire bond between the wire and the bond pad may include an amount of tin originated from a layer of tin alloy formed on the bond pad. In other embodiments, a wirebond structure may include a conductive layer and a layer of tin alloy located over a portion of the conductive layer. The layer of tin alloy may provide a wirebonding contact surface configured to receive a bond wire.

摘要: A semiconductor device includes a bond formed on a bond pad. The bond is formed of a wire that includes a central core of conductive metal, a first coating over the central core of conductive metal that is more chemically active than the conductive metal, and a second coating over the central core of conductive metal that is less chemically active than the central core of conductive metal.
