    • A method for producing a metallic contact face, suitable for tying an electric conductor to it, for contacting a power semiconductor (10), having the following steps: applying a carrier film (20) on the power semiconductor (10) while leaving uncovered the power contacts of the power semiconductor (10); arranging a shaped metal body (30') on the carrier film (20) so that a first section arranged on the carrier film (20) forms a contact face for tying a wire or a ribbon and a second section of the shaped metal body projects above a power contact beyond the face of the carrier film (20), the carrier film (20) forming a single-sided support for the section, projecting beyond the face of the carrier film (20), of the shaped metal body (30'); and connecting the section of the shaped metal body (30') projecting beyond the face of the carrier film (20) to the power contact while deforming the shaped metal body (30'). Alternatively, a method for producing a metallic contact face, suitable for tying an electric conductor to it, for contacting a power semiconductor (10), having the following steps: applying a bond shield having a carrier film (20) and a shaped metal body (30') arranged on the carrier film (20), wherein the shaped metal body (30') comprises a first shaped metal body section arranged on the carrier film (20) and a second shaped metal body section projecting beyond the face of the carrier film (20), and the first shaped metal body section is connected to the second shaped metal body section via a deformation region on the power semiconductor (10), so that the shaped metal body section projecting beyond the face of the carrier foil (20) is arranged above a control or power contact of the power semiconductor (10); and connecting the shaped metal body section, projecting beyond the face of the carrier film (20), with the control or power contact while deforming the shaped metal body (30'). Connecting the section of the shaped metal body (30') projecting beyond the face of the carrier film (20) to the power contact takes place in particular via silver sintering.
