Summary: | In a first vertical field-effect transistor in which first source regions and first connectors each of which electrically connects a first body region and a first source electrode are alternately and periodically disposed in a first direction (Y direction) in which a first trench extends, a ratio of LS [μm] to LB [μm] is at least 1/7 and at most 1/3, where LS denotes a length of one of the first source regions in the first direction, and LB denotes a length of one of the first connectors in the first direction, and LB≤−0.024×(VGS)2+0.633×VGS−0.721 is satisfied for a voltage VGS [V] of a specification value of a semiconductor device, the voltage VGS being applied to a first gate conductor with reference to an electric potential of the first source electrode. |
