Abstract: A nonvolatile semiconductor memory device that have a new structure are provided, in which memory cells are laminated in a three dimensional state so that the chip area may be reduced. The nonvolatile semiconductor memory device of the present invention is a nonvolatile semiconductor memory device that has a plurality of the memory strings, in which a plurality of electrically programmable memory cells is connected in series. The memory strings comprise a pillar shaped semiconductor; a first insulation film formed around the pillar shaped semiconductor; a charge storage layer formed around the first insulation film; the second insulation film formed around the charge storage layer; and first or nth electrodes formed around the second insulation film (n is natural number more than 1). The first or nth electrodes of the memory strings and the other first or nth electrodes of the memory strings are respectively the first or nth conductor layers that are spread in a two dimensional state.

Abstract: The cigarette filter wrapper paper has a paper layer which has a first surface and a second surface. The filter wrapper paper exhibits a first overlap air permeability, measured when a perforated tip paper is overlapped on the first surface, and a second overlap air permeability, measured when a perforated tip paper is overlapped on the second surface. The first overlap air permeability is higher than the second overlap air permeability.
