Distance between each of the first stacked bodies and the second stacked body is longer than distance between adjacent ones of the first stacked bodies. A first void is formed in the interlayer insulating film between the first stacked bodies. A second void is formed in the interlayer insulating film between one of the first stacked bodies and the second stacked body. And, a lower end of the second void is located above a lower end of the first void."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device and method for manufacturing same","description":"A semiconductor memory device includes a semiconductor substrate, a plurality of element isolations, a plurality of first stacked bodies, a second stacked body, and an interlayer insulating film.
