Abstract
A semiconductor device of the present invention includes: an IGBT including an emitter layer on a first main surface side of a semiconductor substrate and a collector layer on a second main surface side of the semiconductor substrate; a freewheeling diode including an anode layer on the first main surface side of the semiconductor substrate and a cathode layer on the second main surface side of the semiconductor substrate; a well region that is located in a boundary between the IGBT and the freewheeling diode and separates the IGBT and the freewheeling diode; a first electrode located on the first main surface of the semiconductor substrate so as to be connected to the emitter layer, the anode layer, and the well region; a resistance element located between the well region and the first electrode.
