Classification: CPC H | IPC H

Claim 12:
13. A semiconductor memory device, comprising:
a semiconductor substrate;
a transistor disposed on the semiconductor substrate;
a stacked body disposed above the transistor, the stacked body including a plurality of first conductive layers stacked in a first direction, a pillar extending through the plurality of first conductive layers in the first direction and containing a semiconductor layer, and a charge storage film disposed between the plurality of first conductive layers and the semiconductor layer;
a first nitride layer disposed above the transistor;
a second nitride layer disposed in a position between the transistor and the first nitride layer in the first direction and having a content of hydrogen different from a content of hydrogen in the first nitride layer; and
a conductor extending through the second nitride layer, the first nitride layer, and the plurality of first conductive layers in the first direction and electrically connected to the transistor.
