The method further includes forming an opening in the second dielectric layer which exposes the first metal layer, forming a second metal layer over the second dielectric layer and within the opening, and forming a second graphene layer on at least one major surface of the second metal layer, wherein the second graphene layer is also formed within the opening."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device with graphene encapsulated metal and method therefor","description":"A method for forming a semiconductor structure includes forming a first metal layer over a first dielectric layer, forming a first graphene layer on at least one major surface of the first metal layer","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9640430","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.
