    Abstract: In a frame member including a first region and a second region that are extending in a first direction in parallel to each other while being spaced apart from each other, first and second plating films are formed in the first and second regions, respectively. The second plating film is different in a type from the first plating film. Then, a stamping process is performed to the frame member including the first region and the second region, thereby a lead frame including a plurality of leads is formed. The lead frame includes a first lead group and a second lead group. The first plating film is formed in the first lead group, but the second plating film is not formed in the first lead group. Meanwhile, the second plating film is formed in the second lead group, but the first plating film is not formed in the second lead group.

    Abstract: A semiconductor device includes a first semiconductor chip including a first MOSFET of n-type and a first parasitic diode and a second semiconductor chip including a second MOSFET of n-type and a second parasitic diode. A first source electrode and a first gate wiring are formed on a first front surface of the first semiconductor chip, and a first drain electrode is formed on a first back surface of the first semiconductor chip. A second source electrode and a second gate wiring are formed on a second front surface of the second semiconductor chip, and a second drain electrode is formed on a second back surface of the second semiconductor chip. The first back surface and the second back surface are faced to each other such that the first drain electrode and the second drain electrode are in contact with each other via a conductive tape.
