The light transmittance of the peeling layer at a wavelength range of 190 nm to 600 nm may be 1 to 90%. The modification caused by absorption of light may be photodecomposition of the novolac resin."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laminated body including novolac resin as peeling layer","description":"A laminated body for polishing a back surface of a wafer, the laminated body including an intermediate layer that is disposed between a support and a circuit surface of the wafer and peelably adheres ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11472168","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.
