The staircase structure includes a plurality of stairs, and a bridge structure in contact with the first memory array structure and the second memory array structure. A stair of the plurality of stairs includes a conductor portion on a top surface of the stair and electrically connected to the bridge structure, and a dielectric portion at a same level and in contact with the conductor portion. The stair is electrically connected to at least one of the first memory array structure and the second memory array structure. The conductor portion includes a portion overlapping with an immediately-upper stair and in contact with the dielectric portion and the bridge structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Staircase structure in three-dimensional memory device and method for forming the same","description":"In an example of the present disclosure, a three-dimensional (3D) memory device includes a memory array structure and a staircase structure dividing the memory array structure into a first memory arra","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12002757","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.
