An upper portion of the active region may include an epitaxial growth layer having a larger lattice constant than silicon (Si), and the source/drain regions and the LDD region may be doped with gallium (Ga)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor devices","description":"A semiconductor device includes: a substrate including a field region that defines an active region; source/drain regions in the active region; a channel region between the source/drain regions; a lig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10490551","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.
