When an IGBT has a barrier layer 10 that separates an upper body region 8a from a lower body region 8b, conductivity modulation is enhanced and on-resistance decreases. When the IGBT also has a Schottky contact region 6 that extends to reach the barrier layer 10, a diode structure can be obtained. In this case, however, a saturation current increases as well as short circuit resistance decreases. The Schottky contact region 6 is separated from the emitter region 4 by the upper body region 8a. By selecting an impurity concentration in the region 8a, an increase in a saturation current can be avoided. Alternatively, a block structure that prevents a depletion layer extending from the region 6 into the region 8a from joining a depletion layer extending from the region 4 into the region 8a may be provided in an area separating the region 6 from the region 4.
