The semiconductor substrate includes a memory cell region and a contact region. The active pillars extend in the memory cell region perpendicularly to the semiconductor substrate. The gate electrodes intersect the active pillars, extend from the memory cell region to the contact region and are stacked on the semiconductor substrate. The supporters extend in the contact region perpendicularly to the semiconductor substrate to penetrate at least one or more of the gate electrodes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile memory device and method for fabricating the same","description":"A three-dimensional nonvolatile memory device and a method for fabricating the same include a semiconductor substrate, a plurality of active pillars, a plurality of gate electrodes, and a plurality of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8541831","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.
