According to one embodiment, a semiconductor storage device includes a plurality of electrode films on a substrate, spaced from one another in a first direction. A charge storage film is provided on a side face the electrode films via a first insulating film. A semiconductor film is provided on a side face of the charge storage film via a second insulating film. The charge storage film includes a plurality of insulator regions contacting the first insulating film, a plurality of semiconductor or conductor regions provided between the insulator regions and another insulator region.

Semiconductor storage device and method for manufacturing semiconductor storage device

In one embodiment, a semiconductor device includes a substrate, insulating films and first films alternately stacked on the substrate, at least one of the first films including an electrode layer and a charge storage layer provided on a face of the electrode layer via a first insulator, and a semiconductor layer provided on a face of the charge storage layer via a second insulator. The device further includes at least one of a first portion including nitrogen and provided between the first insulator and the charge storage layer with an air gap provided in the first insulator, a second portion including nitrogen, provided between the charge storage layer and the second insulator, and including a portion protruding toward the charge storage layer, and a third portion including nitrogen and provided between the second insulator and the semiconductor layer with an air gap provided in the first insulator.
