With this polishing apparatus, it is possible to reduce an amount of displacement caused when moment load is applied on the polishing head during polishing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polishing apparatus and wafer polishing method","description":"A polishing apparatus which is an index system polishing apparatus which includes a polishing head for holding a wafer, a plurality of turn tables to which polishing pads for polishing the wafer are a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10532442","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.
