The well region serves as a base region which controls a current flowing between the potential extracting region and the drift region. Thus, it is possible to provide a novel semiconductor device which is high in reliability while the increase of the chip size can be suppressed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"A semiconductor device includes a first conductive type first main electrode region, a first conductive type drift region which makes contact with the first main electrode region, a first conductive t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9711659","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.
