Abstract:
1. A nonvolatile semiconductor memory device, comprising: a semiconductor substrate; a first layer formed above the semiconductor substrate; a first conductive layer, an inter electrode insulating layer, and a second conductive layer sequentially stacked above the first layer; a memory film formed on an inner surface of each of a pair of through holes provided in the first conductive layer, the inter electrode insulating layer, and the second conductive layer and extending in a stacking direction; a semiconductor layer formed on the memory film in the pair of through holes and partially crystallized; and a metal layer filled in a connection hole that is provided in the first layer and connects lower end portions of the pair of through holes, the metal layer being in contact with the semiconductor layer, and the metal layer separating a first portion of the semiconductor layer in one of the pair of through holes and a second portion of the semiconductor layer in the other of the pair of through holes.
