A process for producing a semiconductor device comprising the steps of: forming a metal wiring layer containing copper as the main component on a semiconductor substrate; forming an insulating film on the entire surface of the resulting semiconductor substrate; removing the insulating film only from a place where a wire of gold or aluminum is to be bonded, in order to expose a part of the metal wiring layer; forming a layer of copper silicide or a layer of a compound of copper and boron in a surface layer of the exposed part of the metal wiring layer; and bonding a wire to a surface of the layer of copper silicide or the layer of the compound of copper and boron. |
