摘要: A semiconductor device comprises a substrate. A plurality of electrode layers and a plurality of insulating layers are formed in an alternating stack above the substrate. A semiconductor column extends through the plurality of electrode layers and the plurality of insulating layers. The semiconductor column comprises a single-crystal semiconductor material on an outer peripheral surface facing the electrode and insulating layers. First insulating films are formed between the semiconductor column and the electrode layers. The first insulating films are spaced from each other along the column length. Each first insulating film corresponds to one electrode layer. A charge storage layer is between each of the first insulating films and the electrode layers. A second insulating film is between the charge storage layer and each of the electrode layers.

摘要: According to one embodiment, columnar portions extend through an insulating layer and through a stacked body under the insulating layer. The columnar portions are of an insulating material different from the insulating layer. Contact portions include a first contact portion disposed inside a first terrace portion and a second contact portion disposed inside a second terrace portion. The columnar portions including a first columnar portion disposed inside the first terrace portion and a second columnar portion disposed inside the second terrace portion. A shortest distance between the first contact portion and the first columnar portion, and a shortest distance between the second contact portion and the second columnar portion are substantially equal to each other.
