The improved structure is capable of reducing FinFET random doping fluctuations when doping is used to control threshold voltage, and the channel structure reduces fluctuations attributable to doping-related variations in effective channel length. Further, the transistor design affords better source and drain conductance when compared to prior art FinFETs. Two representative embodiments of the key structure are described in detail."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fluctuation resistant FinFET","description":"This improved, fluctuation resistant FinFET, with a doped core and lightly doped epitaxial channel region between that core and the gate structure, is confined to the active-gate span because it is ba","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847404","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.
