Patent ID: 8110437

Claim:
A method, comprising: mounting a semiconductor chip on a first surface of a thermally and electrically conductive connector formed entirely of an electrically conductive material and arranged in or on a plastic encapsulant, wherein the encapsulant comprises a thermoplast material and a filler material and the encapsulant contacts at least a portion of a surface of the connector opposite the first surface; wherein a connection between the chip and the connector is produced by a soft soldering process using a soft solder material, the soft soldering process taking place at a temperature of between 200° C. inclusive and 260° C. inclusive, and a gold film is deposited on the soft solder material before soldering; wherein the soft solder material comprises substantially an alloy whose material system has a eutectic composition; and wherein layers comprising different components of the alloy are applied to said semiconductor chip and/or to said connector.
