| 20120241843 | NONVOLATILE SEMICONDUCTOR MEMORY DEVICE AND METHOD FOR MANUFACTURING SAME - According to one embodiment, a nonvolatile semiconductor memory device includes a memory cell array part, a first contact part, and a peripheral circuit part. The first contact part is juxtaposed with the memory cell array part in a first plane. The peripheral circuit part is juxtaposed with the memory cell array part in the first plane. The memory cell array part includes a first stacked body, a first semiconductor layer, and a memory film. The first contact part includes a first contact part insulating layer, and a plurality of first contact electrodes. The peripheral circuit part includes a peripheral circuit, a structure body, a peripheral circuit part insulating layer, and a peripheral circuit part contact electrode. A width along an axis perpendicular to the first axis of the peripheral circuit part insulating layer is smaller than a diameter of the first particle. | 09-27-2012 |
