Abstract

PURPOSE:To decrease the grounding lead inductance of a semiconductor device by shortcircuiting between either one electrode of source and drain electrodes and the back surface electrode of the device via a metallic layer or a solder. CONSTITUTION:When a source electrode 2 is grounded to a case, a metallic layer 9 is formed on the side face of a dicing groove 7, a semiconductor substrate 1a is etched from the back surface of the substrate 1 to the vicinity of the groove 7, a metallic electrode 10 is then formed on the back surface, and a semiconductor device is mounted on the case with mounting solder. Thus, the electrode 2 is grounded via the layer 9, the electrode 10 and the mounting solder.
