Abstract:
According to one embodiment, a nonvolatile semiconductor memory device includes a plurality of U-shaped memory strings, each of the plurality of U-shaped memory strings including a first columnar body, a second columnar body, and a conductive connection body. The conductive connection body connects the first columnar body and the second columnar body. A plurality of first memory cells are connected in series in the first columnar body and are composed of a plurality of first conductive layers, a first inter-gate insulating film, a plurality of first floating electrodes, a first tunnel insulating film, and a first memory channel layer. The plurality of first floating electrodes are separated from the plurality of first conductive layers by the first inter-gate insulating film. A plurality of second memory cells are connected in series in the second columnar body, similarly to the plurality of first memory cells.

Claim (Index 18):
A method of manufacturing a nonvolatile semiconductor memory device, the device including:\n a plurality of first memory cells stacked in a first direction and electrically connected in series; the first memory cells including:\n a first semiconductor body extending in the first direction; \n a plurality of first floating electrodes provided on a side surface of the first semiconductor body interposed a first insulating layer, the first floating electrodes being stacked in the first direction; \n a plurality of first conductive layers stacked in the first direction, one of the first conductive layers being provided on a side surface of one of the first floating electrodes interposed a second insulating layer; \n a plurality of second memory cells stacked in the first direction and electrically connected in series, the second memory cells being provided beside the first memory cells; the second memory cells including:\n a second semiconductor body extending in the first direction and being provided beside the first semiconductor body; \n a plurality of second floating electrodes provided on a side surface of the second semiconductor body interposed a third insulating layer, the plurality of second floating electrodes being stacked in the first direction; \n a plurality of second conductive layers stacked in the first direction, one of the second conductive layers being provided on a side surface of one of the second floating electrodes interposed a fourth insulating layer; and a silicide-containing connection member including metal silicide, the silicide-containing connection member being connected to one end of the first memory cells and one end of the second memory cells, the method comprising: forming the silicide-containing connection member on an insulating layer provided above a substrate; forming a stacked body in which the first memory cells and the second memory cells being to be formed above the silicide-containing connection member; the stacked body including a plurality of conductors stacked in the first direction, the first conductive layers and the second conductive layers being composed of the conductors; forming a first hole and a second hole extending in the first direction through the stacked body and reaching the silicide-containing connection member; and depositing a semiconductor film in the first hole and the second hole to form the first semiconductor body and the second semiconductor body, the semiconductor film being formed on the silicide-containing connection member exposed at bottoms of the first hole and the second hole.
