Abstract:
A semiconductor memory device includes a conductive layer; a first electrode layer provided above the conductive layer; a second electrode layer provided between the conductive layer and the first electrode layer; a first semiconductor channel body extending through the first electrode layer in a first direction from the conductive layer to the first electrode layer; a second semiconductor channel body provided between the conductive layer and the first semiconductor channel body, the second semiconductor channel body extending through the second electrode layer; and an insulating layer provided between the second semiconductor channel body and the second electrode layer. The second semiconductor channel body includes a first recessed portion in a lateral surface facing the second electrode layer, and the second electrode layer includes a second recessed portion in a surface facing the second semiconductor channel body.

Claim (Index 15):
A method for manufacturing a semiconductor memory device, the method comprising:\n forming a stacked body including a plurality of interlayer insulating layers and a plurality of sacrificial layers, the interlayer insulating layers and the sacrificial layers being alternately stacked in a first direction; forming a memory hole extending in the first direction through the stacked body; selectively removing portions of the plurality of sacrificial layers exposed on an inner wall of the memory hole; oxidizing parts of the plurality of sacrificial layers exposed in the inner wall of the memory hole; forming a columnar body in the memory hole, the columnar body including a first insulating layer, a charge storage layer, a second insulating layer and a semiconductor layer sequentially stacked on the inner wall of the memory hole; selectively removing the sacrificial layers; and forming a plurality of electrode layers in spaces formed by removing the plurality of sacrificial layers.
