Abstract:
According to one embodiment, a semiconductor device includes a stacked body, a memory cell array, and a columnar portion. The stacked body is provided on a major surface of a substrate. The stacked body includes a plurality of electrode layers stacked with an insulating body interposed. The memory cell array is provided inside the stacked body. The columnar portion is provided inside the memory cell array. The columnar portion extends along a stacking direction of the stacked body. The columnar portion includes a semiconductor body and a memory film. The memory film includes a charge storage portion. The substrate includes a first contact portion contacting the semiconductor body. A configuration of the first contact portion is convex along the stacking direction.

Claim (Index 1):
A method for manufacturing a semiconductor device, comprising:\n forming a structure body on a substrate, the structure body including an insulating body; forming a mask layer on the structure body, the mask layer including a hole pattern, the hole pattern including an island pattern on an inner side of the hole pattern; and forming an opening in the structure body by using the mask layer as a mask.
