In the semiconductor device, in a diode formed of a P-N junction including an anode P-type layer formed in the main surface of a semiconductor substrate and a back surface N+-type layer formed in the back surface of the semiconductor substrate, a back surface P+-type layer is formed in the back surface, and a surface P+-type layer is formed in the main surface right above the back surface P+-type layer to thereby promote the effect of hole injection from the back surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"In a back surface hole injection type diode, by more effectively securing the effect of hole injection from the back surface of a semiconductor substrate, the performance of a semiconductor device is ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9768286","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.
