A semiconductor device includes a semiconductor substrate, a source electrode, a drain electrode, a plurality of trenches, a plurality of first electrodes disposed in a plurality of trenches by way of gate insulation films formed on side walls of the plurality of respective trenches, a plurality of second electrodes disposed above the plurality of first electrodes in a state where the second electrodes are spaced apart from the first electrodes, a plurality of first insulation regions, and a plurality of second insulation regions. The trenches, the first electrodes and the second electrodes are formed in stripes as viewed in a plan view. At least one of the plurality of second electrodes is connected to the drain electrode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and method of manufacturing semiconductor device","description":"Provided is a semiconductor device in which a snubber-circuit is incorporated and can realize downsizing of a power conversion circuit into which the semiconductor device is assembled, and is flexibly","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11978793","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.
