An element isolation region having an upper surface lower than a main surface of the semiconductor substrate is formed inside a trench in the main surface of the semiconductor substrate, so that a void formed immediately above the semiconductor substrate in an active region and a void formed immediately above the element isolation region are divided from each other. In this manner, a conductive film is prevented from being buried in the second void."},"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 the same","description":"When a void is caused in an interlayer insulating film on a semiconductor substrate, the invention prevents short circuit between two or more contact plugs that sandwich the void therebetween via a co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10490445","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.
