Abstract
A semiconductor device semiconductor chip mounted to a leadframe that includes an electrically conductive pad. An electrically conductive clip is arranged in a bridge-like position between the semiconductor chip and the electrically conductive pad. The electrically conductive clip is soldered to the semiconductor chip and to the electrically conductive pad via soldering material applied at coupling surfaces facing towards the semiconductor chip and the electrically conductive pad. The device further includes a pair of complementary positioning formations formed by a cavity in the electrically conductive clip and a protrusion (such as a stud bump or a stack of stud bumps) formed in the electrically conductive pad. The complementary positioning formations are mutually engaged to retain the electrically conductive clip in the bridge-like position to avoid displacement during soldering.
