Abstract:
According to one embodiment, a method for manufacturing a semiconductor memory device includes simultaneously forming a plurality of first holes and a plurality of second holes in a stacked body. The stacked body includes a plurality of first layers and a plurality of second layers. The method includes etching a portion between the second holes next to each other in the stacked body, and connecting at least two or more second holes to form a groove. The method includes forming a film including a charge storage film on a sidewall of the first holes. The method includes forming a channel film on a sidewall of the film including the charge storage film.

Claim (Index 36):
A semiconductor memory device comprising:\n a stacked body including a plurality of electrode layers stacked with insulators interposed between the electrode layers, the electrode layers including at least a first electrode layer and a second electrode layer provided below the first electrode layer, the first electrode layer functioning a control gate of a memory cell and the second electrode layer functioning a control gate of a select transistor; a plurality of columnar portions arranged in a staggered arrangement so as to penetrate through the electrode layers in a stacking direction of the stacked body, each of the columnar portions including a semiconductor film extending in the stacking direction and a cylindrical film provided between the electrode layers and the semiconductor film; and a separation portion extending in the stacking direction and in a first direction intersecting the stacking direction, and separating the stacked body into a first portion and a second portion of the stacked body in a second direction intersecting the stacking direction and the first direction, the separation portion being disposed between the first portion and the second portion of the stacked body so that the first portion and the second portion have a pair of sidewalls facing each other with the separation portion interposed, the pair of sidewalls including a sidewall on the first portion side and a sidewall on the second portion side, a plurality of first concave portions being disposed at the sidewall on the first portion side along the first direction, a plurality of second concave portions being disposed at the sidewall on the second portion side along the first direction, and the first concave portions and the second concave portions having asymmetric positional relationship in the first direction with respect to a central axis of the separation portion along the first direction.
