Claim Text:
1. A method for manufacturing a nonvolatile storage device, comprising the steps of: (a) forming, on a semiconductor substrate, a first conductive layer extended in a first direction along a main surface of the semiconductor substrate; (b) forming, on the first conductive layer, a stacked film in which (N+1) (N is an integer of N≧1) first insulator films and N second conductive layers are alternately stacked together; (c) forming a third conductive layer on the stacked film; (d) forming a second insulator film on a side wall of the stacked film, and forming a first semiconductor layer and a memory material layer, which are electrically connected to the third conductive layer, on a sidewall of the second insulator film including on a portion of said second insulator film which extends beyond and is not in contact with the stacked film; and (e) after the step (d), forming, on the third conductive layer, a fourth conductive layer electrically connected to the third conductive layer, and extended in a second direction orthogonal to the first direction.
