Abstract

A transistor and a diode are formed on a common semiconductor substrate; the semiconductor substrate has a transistor region and an outer peripheral region surrounding it; the transistor region is divided into a plurality of channel regions and a plurality of non-channel regions by a plurality of gate electrodes each having a stripe shape; each of the plurality of non-channel regions has a first semiconductor layer, a second semiconductor layer, a third semiconductor layer, a fifth semiconductor layer, a first electrode, and a second electrode; the third semiconductor layer and the fifth semiconductor layer are electrically connected to the second electrode via a contact hole; and the fifth semiconductor layer is selectively provided not to be in contact with an impurity layer of a first conductivity type that is provided in the outer peripheral region and defines a boundary with a cell region.
