In the embodiments of the present disclosure, the contact plug is in contact with a top surface of the source/drain doped layer as well as the side walls, which are close to the second dielectric layer and away from the second dielectric layer respectively, of the source/drain doped layer, so that a contact resistance between the contact plug and the source/drain doped layer is relatively small, thereby improving the electrical performance of the semiconductor structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor structure and forming method for thereof","description":"A semiconductor structure and a forming method thereof are provided, where one form of a forming method includes: providing a substrate, where the substrate includes a first region and a second region","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11996460","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.
