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 25):
The device according to  claim 21 , further comprising a underlying silicon portion below the stacked body, lower ends of a first semiconductor film, a second semiconductor film and a third semiconductor film being connected to the underlying silicon portion in common, the first semiconductor film, the second semiconductor film and the third semiconductor film being respectively included in the first columnar portion, the second columnar portion and the third columnar portion.
