Abstract
A semiconductor storage device includes a semiconductor substrate and a conductive layer separated from the semiconductor substrate in a first direction. The conductive layer extends in a second direction parallel to the semiconductor substrate. A semiconductor layer extends in the first direction through the conductive layer. A first contact extends in the first direction and is connected to a surface of the conductive layer facing away from the semiconductor substrate. A first insulating layer extends in the first direction, and a second insulating layer extends along the first insulating layer in the first direction. Each of the first and second insulating layers entirely overlaps with the first contact when viewed in the first direction.
