Abstract

All of four of built-in gate resistance trenches function as practical built-in gate resistance trenches. A first end portion of each of four of the built-in gate resistance trenches is electrically connected to a wiring side contact region of a gate wiring via a wiring contact. A second end portion of each of four of the built-in gate resistance trenches is electrically connected to a pad side contact region of a gate pad via a pad contact. In each of four of the built-in gate resistance trenches, a distance between the wiring contact and the pad contact is defined as an inter-contact distance.
