The first trench comprises a bottom surface on the underlying and two side surfaces joined to the bottom surface, formed into a U-shape. The first graphene layer has a stacked structure including a plurality of graphene sheets. The plurality of graphene sheets each include a depression in a central portion. Portions of the graphene sheets located in an edge of the first graphene layer are each extended upward, which is in a direction opposite to the bottom surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and manufacturing method thereof","description":"According to one embodiment, a semiconductor device includes a first insulating layer on an underlying layer, a first trench formed in the first insulating layer, and a first graphene layer provided i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9646933","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.
