The gate electrode is configured to control current flow between the source region and the drain region along at least a first side wall of the gate trench. The trench transistor further includes a doped semiconductor region having dopants introduced into the semiconductor body through an unmasked part of the walls of a trench."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Trench transistor having a doped semiconductor region","description":"A trench transistor having a semiconductor body includes a source region, a body region, a drain region electrically connected to a drain contact, and a gate trench including a gate electrode which is","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9711621","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.
