The epitaxial feature includes two lower portions and one upper portion. The two lower portions are over the two fins respectively. The upper portion is over the two lower portions and connects the two lower portions. The upper portion has a different dopant concentration than the two lower portions. A top surface of the upper portion is substantially flat."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"FinFET device having flat-top epitaxial features and method of making the same","description":"A semiconductor device includes a substrate, an isolation structure over the substrate, two fins over the substrate and protruding out of the isolation structure, and an epitaxial feature over the two","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10490552","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.
