Abstract: To improve the reliability in applying a tape to the rear surface of a substrate while securing the heat resistance of the tape applied to the rear surface of the substrate. There is a gap between a bottom surface of a ditch provided in a support member and an upper surface of a driver IC chip. On the other hand, the upper surface side of a lead frame is supported by the support member so that the bottom surface of the ditch contacts the upper surface of a Low-MOS clip mounted over a Low-MOS chip. Thus, even in a state where the driver IC chip and the Low-MOS chip are mounted on the upper surface side of the lead frame, the tape can be reliably applied to the rear surface of the lead frame (in particular, to the rear surface of the product region).

Abstract: To enhance the reliability of connection between a semiconductor chip and a metal plate by ensuring sufficiently the thickness of a conductive material interposed between the semiconductor chip and the metal plate. A lead frame is arranged over a jig and a clip frame is arranged over protruding portions provided on the jig. In this state, a heating process (reflow) is performed. In this case, high melting point solders filling first spaces are melted in a state in which the first space is formed between a High-MOS chip and a High-MOS clip and the first space is formed between a Low-MOS chip and a Low-MOS clip. At this time, even when the high melting point solder is melted in the first space, the size (in particular, the height) of the first space does not change and the first space is maintained.

Abstract: To prevent, in a resin-sealed type semiconductor package, generation of cracks in a die bonding material used for mounting of a semiconductor chip. A semiconductor chip is mounted over the upper surface of a die pad via a die bonding material, followed by sealing with an insulating resin. The top surface of the die pad to be brought into contact with the insulating resin is surface-roughened, while the bottom surface of the die pad and an outer lead portion are not surface-roughened.
