Claim Text:
1. A method for manufacturing a nonvolatile semiconductor memory device including a stacked structure body including a plurality of electrode films stacked along a first direction and an inter-electrode insulating film provided between the electrode films, a semiconductor layer opposed to side faces of the electrode films, an organic film provided between the side faces of the electrode films and the semiconductor layer and containing an organic compound, a semiconductor-side insulating film provided between the organic film and the semiconductor layer, and an electrode-side insulating film provided between the organic film and the side faces of the electrode films, the method comprising: alternately stacking a plurality of first films and a plurality of second films along the first direction to form a base body, the base body being to be at least part of the stacked structure body; forming a through hole penetrating through the base body along the first direction and burying a semiconductor in the through hole to form the semiconductor layer; removing the plurality of first films; forming an insulating film on a side face of the semiconductor layer exposed by removing the plurality of first films to form the semiconductor-side insulating film; forming the organic film on the semiconductor-side insulating film; forming the electrode-side insulating film on the organic film; and forming a conductive film on the electrode-side insulating film to form the electrode films, wherein the organic film is bonded to the semiconductor-side insulating film by at least one of an ether linkage, a silyl ether linkage, an ester linkage, a thioether linkage.
