Coated bonding wire and methods for bonding using same

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 o...

Zusammenfassung: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.
