The nonuniform trench shape may reduce back channel leakage by providing an effective channel directly below a gate stack having a width that is less than a width of an effective back channel directly above the isolation layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Junction butting structure using nonuniform trench shape","description":"The present invention relates generally to semiconductor devices and more particularly, to a structure and method of forming a partially depleted semiconductor-on-insulator (SOI) junction isolation st","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9627480","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.
