Abstract
According to one embodiment, a semiconductor device includes a substrate; a first structure; a second structure; a step; an insulating layer; a first pillar; a second pillar; a first contact portion; and a second contact. The first structure includes a first electrode layer and a first insulator. The first structure has a first terrace on a surface of the first insulator. The second structure includes a second electrode layer and a second insulator. The second structure has a second terrace on a surface of the second insulator. The second contact portion is electrically connected to the second electrode layer via the second terrace. The first contact portion is located between the step and the first pillar. The step is located between the first contact portion and the second pillar.
