Abstract
A first conductor extends in a first direction. A first semiconductor surrounds the first conductor along a first plane intersecting the first direction. A first insulator surrounds the first semiconductor along the first plane. A second conductor surrounds the first insulator along the first plane. A third conductor is located farther in the first direction than the first semiconductor and surrounds the first conductor along the first plane. A second insulator is between the first semiconductor and the third conductor.
