A first local wiring includes a convex portion protruding from a base and a protrusion protruding from a side surface of the convex portion. The convex portion of the first local wiring is connected to a lower conductive region of a first transistor while the protrusion is connected to a gate electrode of a second transistor. Moreover, the lower surface of the protrusion of the first local wiring is arranged at a height equal to or lower than the upper surface of the gate electrode of the second transistor.
