Abstract:
1. A semiconductor device comprising: a substrate; a first circuit portion provided on the substrate, the first circuit portion including: a first switching element including a first electrode and a second electrode, a first diode including a first cathode electrode connected to the first electrode and a first anode electrode connected to the second electrode, a second switching element including a third electrode connected to the second electrode and a fourth electrode, and a second diode including a second cathode electrode connected to the third electrode and a second anode electrode connected to the fourth electrode; and a second circuit portion provided on the substrate, the second circuit portion including a third switching element including a fifth electrode and a sixth electrode, a third diode including a third cathode electrode connected to the fifth electrode and a third anode electrode connected to the sixth electrode, a fourth switching element including a seventh electrode connected to the sixth electrode and an eighth electrode, and a fourth diode including a fourth cathode electrode connected to the seventh electrode and a fourth anode electrode connected to the eighth electrode, the first switching element being juxtaposed with the second switching element in a first direction along the substrate, and being juxtaposed with the fourth switching element in a second direction that intersects with the first direction along the substrate, the third switching element being juxtaposed with the fourth switching element in the first direction, and being juxtaposed with the second switching element in the second direction, a direction from the first switching element toward the second switching element being opposite to a direction from the third switching element toward the fourth switching element, a voltage of a first polarity being applied to the first electrode and the fifth electrode, and a voltage of a second polarity opposite the first polarity being applied to the fourth electrode and the eighth electrode.
