Patent ID: 7952136

Claim:
A nonvolatile semiconductor storage apparatus comprising: a substrate; an insulating layer disposed on the substrate; a columnar semiconductor disposed perpendicular to the substrate; a laminated film comprising: a first insulating film disposed around the columnar semiconductor, a charge storage film disposed around the first insulating film, and a second insulating film disposed around the charge storage film; a first conductor layer that is disposed on the insulating layer and that is in contact with the laminated film; a first interlayer insulating layer disposed on the first conductor layer; a second conductor layer that is disposed on the first interlayer insulating layer and that is in contact with the laminated film; a first contact plug that is connected to the first conductor layer; and a second contact plug that is connected to the second conductor layer; wherein the first conductor layer comprises a first end portion that is bent upwardly in a direction perpendicular to a surface of the substrate; wherein the second conductor layer comprises a second end portion that is bent upwardly in the direction perpendicular to a surface of the substrate; wherein the first end portion comprises a first end face; wherein the second end portion comprises a second end face; wherein the first contact plug is disposed on the first end face; and wherein the second contact plug is disposed on the second end face.
