The solder layer includes an inner solder portion positioned inner than an end portion of the metal member and an outer solder portion positioned outer than the end portion of the metal member, relative to a direction along the front surface of the semiconductor substrate. The semiconductor substrate includes an inner substrate portion positioned below the inner solder portion and an outer substrate portion positioned below the outer solder portion. A density of carriers that flow from the outer substrate portion to the front surface electrode is lower than a density of carriers that flow from the inner substrate portion to the front surface electrode."},"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 semiconductor substrate, a front surface electrode provided on a front surface of the semiconductor substrate, a solder layer, and a metal member fixed to a front sur","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9607961","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.
