Abstract

According to an embodiment of the invention, a semiconductor device includes a base body that includes silicon carbide, a first semiconductor member that includes silicon carbide and is of a first conductivity type, and a second semiconductor member that includes silicon carbide and is of a second conductivity type. A first direction from the base body toward the first semiconductor member is along a [0001] direction of the base body. The second semiconductor member includes a first region, a second region, and a third region. The first semiconductor member includes a fourth region. A second direction from the first region toward the second region is along a [1-100] direction of the base body. The fourth region is between the first region and the second region in the second direction. A third direction from the fourth region toward the third region is along a [11-20] direction of the base body.
