Abstract:
A semiconductor device comprising:a first conductor having a plane surface; semiconductor chips each having a first surface arranged adjacent the plane surface, and having a first main electrode arranged on the first surface and electrically connected to the first conductor, a second main electrode arranged on a back surface of the first surface, and a control electrode arranged on the back surface of the first surface and configured to switch a current flowing between the first main electrode and the second main electrode; a second conductor electrically connected to the second main electrode and having columns each having an upper surface arranged below each of the semiconductor chips and equal to the number of the semiconductor chips; and a circuit board having openings penetrated by the columns, the number of the openings being equal to the number of the semiconductor chips and having a first insulating film, a first conductive film arranged on a peripheral portion of the first insulating film on a second surface of the first insulating film and electrically connected to one of the control electrode and the second conductor, and a second conductive film arranged on a back surface of the second surface of the first insulating film and the peripheral portion above the first conductive film and electrically connected to the other of the control electrode and the second conductor.
