The device further includes a plurality of pillar portions, each of which including a first insulator, a charge storage layer, a second insulator, a first semiconductor layer and a third insulator that are sequentially provided in the stacked film and the second insulating layer. Furthermore, a width of the second insulating layer sandwiched between the pillar portions is narrower than a width of the stacked film sandwiched between the pillar portions, in at least a portion of the second insulating layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor storage device and method of manufacturing the same","description":"In one embodiment, a semiconductor storage device includes a substrate, a stacked film including a plurality of first insulating layers and a plurality of electrode layers that are alternately provide","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11488972","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
