The arrangements of dummy gate structures and the ranges of metal pattern density have been described. Wide gate structures, such as analog devices, can greatly benefit from the reduction of dishing effect."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dummy metal gate structures to reduce dishing during chemical-mechanical polishing","description":"The described embodiments of mechanisms for placing dummy gate structures next to and/or near a number of wide gate structures reduce dishing effect for gate structures during chemical-mechanical poli","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9601489","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.
