摘要:
According to one embodiment, a semiconductor device includes a substrate, a first stacked body, a memory film, a first channel body, a second stacked body, a gate insulating film and a second channel body. A step part is formed between a side face of the select gate and the second insulating layer. A film thickness of a portion covering the step part of the second channel body is thicker than a film thickness of a portion provided between the second insulating layers of the second channel body.
