Patent ID: 10840261

Abstract:
A semiconductor storage device includes a base portion, a stacked body, and a first column. The base portion includes a substrate, a semiconductor element on the substrate, lower-layer wiring above the semiconductor element, and a first conductive layer above the lower-layer wiring and made of a metal compound or polycrystal silicon. The stacked body is above the first conductive layer. The stacked body includes second conductive layers and insulating films stacked alternately. The first column includes a semiconductor body and a memory film. The semiconductor body extends in a stacked direction of the stacked body and is electrically connected to the first conductive layer. A memory film has a charge trap between the plurality of second conductive layers and the semiconductor body. The first conductive layer is provided between the stacked body and the lower-layer wiring, and between a peripheral region of the stacked body and the lower-layer wiring.
