Abstract:
1. A semiconductor device comprising: a semiconductor die having a surface with a control bonding pad of a first metal and a terminal bonding pad of the first metal formed on said surface; a lead frame comprising a second metal control lead and terminal leads; and a first bond wire comprising a core of the first metal with a coating comprising nickel, said first bond wire bonded at one end to the control bonding pad and at the other end to a control lead of the lead frame, and a second bond wire comprising a core of the first metal with a coating of nickel, said second bond wire bonded at one end to the terminal bonding pad and at the other end to a terminal lead of the lead frame; wherein the bonds of the bond wires to the bond pads forms a metallurgic bond of nickel and the first metal and the bond of the bond wires to the leads forms a metallurgical bond of nickel and the first and second metals.
