Abstract:
A semiconductor memory device includes a substrate, a first stacked body provided in a first region on the substrate, a transistor formed in a second region of the substrate, and a block member provided between the first stacked body and the transistor. The first stacked body includes a plurality of first silicon oxide films and a plurality of electrode films stacked alternately one by one. Diffusion coefficient of hydrogen in the block member is lower than diffusion coefficient of hydrogen in silicon oxide.

Claim (Index 29):
A method for manufacturing a semiconductor memory device, comprising:\n digging a first region of a substrate so that an end part is shaped like an inclined surface; forming a first stacked film on the substrate by alternately forming first silicon oxide films and first silicon nitride films by a low pressure chemical vapor deposition method; forming a second stacked film on the first stacked film by alternately forming second silicon oxide films and second silicon nitride films by a normal pressure chemical vapor deposition method; etching the second stacked film and the first stacked film to process an end part of the first stacked film and the second stacked film in a staircase shape in which a terrace is formed for each of the first silicon nitride films and each of the second silicon nitride films; and replacing the first silicon nitride films and the second silicon nitride films by electrode films.
