The gate structure wraps around the channel structure. The first source/drain epitaxial structure and the second source/drain epitaxial structure are disposed on opposite endings of the channel structure. The gate contact is disposed on the gate structure. The back-side source/drain contact is disposed under the first source/drain epitaxial structure. The first source/drain epitaxial structure has a concave bottom surface contacting the back-side source/drain contact."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitance reduction for back-side power rail device","description":"A semiconductor transistor device includes a channel structure, a gate structure, a first source/drain epitaxial structure, a second source/drain epitaxial structure, a gate contact, and a back-side s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11289606","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.
