Claim:
1. A method for manufacturing a semiconductor device, comprising: molding a sealing resin layer, including an inorganic filler therein, on a surface of a substrate which includes a plurality of semiconductor elements attached thereto by an adhesive, the substrate further including external input and output terminals disposed on another surface thereof electrically connected to the semiconductor elements; cutting the molded substrate so as to expose a conductive body therein having a terminal portion electrically connectable to an external input and output terminal, the external input and output terminal configured to be connectable to a ground potential; positioning the cut molded substrates in a tray such that a surface of the sealing resin layer is exposed and an opposed surface of the cut molded substrate faces a surface of the tray; sputter-etching, in a sub-atmospheric pressure environment, the exposed surface of the sealing resin layer; and sputtering a metal layer over the sealing resin layer and the cut portion of the molded substrate in a sub-atmospheric pressure environment to electrically connect the metal layer to the conductive body on the surface of the cut surface while the cut molded substrate is located on the tray, wherein during the sputter-etching, at least a portion of the inorganic filler in the sealing resin is exposed.
