The semiconductor integrated circuit includes a first well region of the first conductivity type and a second well region of the second conductivity type provided in an upper portion of the first well region. The first current suppression layer is separated from the first well region and the second current suppression layer is provided under the first current suppression layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of manufacturing semiconductor integrated circuit","description":"A method of manufacturing a semiconductor integrated circuit includes a first ion implantation process implanting impurity ions of a second conductivity type into a bottom surface of a semiconductor s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11233052","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.
