Abstract:
A semiconductor memory device includes a substrate with a first insulating film thereon, a wiring in the first insulating film, a first electrode film on the first insulating film, a stacked body on the first electrode film, made of alternating second insulating films and second electrode films, a first insulating member extending in a direction to penetrate the stacked body, a first semiconductor film around the first insulating member and connected to the first electrode film, a third insulating film around the first semiconductor film, a first conductive member extending in the direction to penetrate the stacked body and the first electrode film, and connected to the wiring, and a fourth insulating film around the first conductive member. The fourth insulating film has the same film structure as the third insulating film.

Claim (Index 13):
A method for manufacturing a semiconductor memory device, the method comprising:\n forming a first insulating film on a semiconductor substrate, the first insulating film including a wiring therein; forming a first electrode film on the first insulating film; forming a stacked body on the first electrode film by alternately stacking second insulating films and first films along a first direction; processing an end portion of the stacked body in a second direction into a stair shape with a terrace formed at each of the first films, the second direction crossing the first direction; forming a third insulating film to cover the end portion; forming a first hole extending in the first direction through the stacked body, and forming a second hole through the stacked body and the first electrode film;\n forming a fourth insulating film on inner surfaces of the first and second holes by depositing a first insulating material; \n forming a semiconductor film on a surface of the fourth insulating film by depositing a semiconductor material; \n forming an insulating member on a surface of the semiconductor film and in the first and second holes by depositing a second insulating material; \n forming a slit extending in the first direction in the stacked body; \n removing material of the first film via the slit; \n forming a second electrode film in a space formed by removing the material of the first film; \n forming a third hole in the insulating member inside the second hole to the wiring; \n forming a fourth hole in the third insulating film to reach the second electrode film; and \n forming a first conductive member in the third hole that connects to the wiring and forming a second conductive member in the fourth hole that connects to the second electrode film, by depositing a conductive material.
