Abstract:
According to one embodiment, a stacked body includes a plurality of conductive layers stacked with an insulator interposed. The stacked body includes a first stacked portion and a second stacked portion. The second stacked portion includes a plurality of terrace portions arranged in a staircase configuration with level differences in a first direction and a second direction. The second stacked portion includes a conductive portion and a spacer portion. The conductive portion is connected to the conductive layer and is provided in same layer as the conductive layer. The spacer portion is provided in same layer as the conductive layer and the conductive portion. The spacer portion is of a material different from the conductive portion.

Claim (Index 16):
A method for manufacturing a semiconductor device, comprising:\n forming a plurality of terrace portions arranged in a staircase configuration with level differences in a portion of a stacked body, the stacked body including a plurality of first layers and a plurality of second layers, the first layers and the second layers including a first layer and a second layer stacked alternately; forming a plurality of columnar portions in a first stacked portion of the stacked body, the first stacked portion not including the terrace portions; forming a first space after the forming of the columnar portions by removing the first layer of the first stacked portion by etching through a plurality of first slits formed in the first stacked portion; forming a second space by performing etching through a plurality of second slits formed in a second stacked portion including the terrace portions, the etching removing one portion of the first layer of the second stacked portion adjacent to the second slits while causing another portion of the first layer to remain in the second stacked portion; and forming a conductive material inside the first space and inside the second space, the conductive material being continuous inside the first space and inside the second space.
