Abstract
A storage device includes a conductive layer, a plurality of electrode layers stacked on the conductive layer, a wiring above the plurality of electrode layers, an interlayer insulating film between the plurality of electrode layers and the wiring, a semiconductor film penetrating the plurality of electrode layers and the interlayer insulating film in a stacking direction of the plurality of electrode layers, a contact plug penetrating the interlayer insulating film in the stacking direction, and connected to each of the plurality of electrode layers, and a conductive film in the vicinity of the contact plug and penetrating at least one of the plurality of electrode layers in the stacking direction. The semiconductor film is electrically connected to the conductive layer and the wiring, and an entire upper end of the conductive film is covered by an insulating layer.
