The backside contact may include selectively etching from the backside a first trench extending to expose a first source/drain structure and a second trench extending to a second source/drain structure. A conductive layer is deposited in the trenches and patterned to form a conductive via to the first source/drain structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device having backside via and method of fabricating thereof","description":"Structures and methods that include a device such as a gate-all-around transistor formed on a frontside and a contact to one terminal of the device from the frontside of the structure and one terminal","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11239325","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.
