A semiconductor device exhibits a first metal layer, made of a first metal, with at least one contiguous subsection. At least one second metal layer, made of a second metal, is placed on the contiguous subsection of the first metal layer. The second metal is harder than the first metal. The second metal layer is structured to form at least two layer regions, which are disposed on the contiguous subsection of the first metal layer. The second metal exhibits a boron-containing or phosphorus-containing metal or a boron-containing or phosphorus-containing metal alloy.

The invention relates to a method for fabricating a bond by providing a body including a metallic surface provided with an inorganic, dielectric protective layer. The protective layer covers at least one surface zone of the metallic surface in which the metallic surface is to be electrically conductive bonded to a contact conductor. To fabricate the bond, a portion of a provided contact conductor above the surface zone is pressed on to the protective layer and the body so that the protective layer is destroyed above the surface zone in achieving an electrically conductive bond between the metallic surface and the contact conductor.

One aspect relates to a bonding apparatus for producing a bonding connection between a bonding wire and a bonding partner. The bonding apparatus includes a heel shaper, which is provided for avoiding damage to the bonding wire in the heel region during the bonding operation.One aspect relates to a method for producing a bonding connection by means of a bonding apparatus having a heel shaper and a bonding stamp. The heel shaper is situated relative to the bonding stamp in a first active position or can be moved into such a first active position. In the first active position, the heel shaper ensures that the bonding wire runs in a permissible region in the heel region.
