Abstract
A semiconductor device includes a semiconductor layer having a first surface in which a plurality of trenches each extending along a first direction are arranged along a second direction perpendicular to the first direction, a first electrode on a second surface of the semiconductor layer, a second electrode on the first surface of the semiconductor layer, and a control electrode inside at least one of the trenches. The plurality of trenches includes first, second, and third trenches. The first and second trenches are connected to each other via a first connector at an end in the first direction of each of the first and second trenches. The third trench extends beyond the end of each of the first and second trenches along the first direction.
