A shoulder portion is provided on a side wall of the gate trench between the top end of the gate conducting portion and the front surface of the semiconductor substrate and has an average slope, relative to a depth direction of the semiconductor substrate, that is greater than a slope of the side wall of the gate trench at a position opposite the top end of the gate conducting portion, and a portion of the first region that contacts the gate trench is formed as a deepest portion thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device including a shoulder portion and manufacturing method","description":"A semiconductor device including a semiconductor substrate; a trench formed in a front surface of the semiconductor substrate; a gate conducting portion formed within the gate trench; and a first regi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505028","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.
