The present invention, by using a surface protection sheet, protects a circuit side of a wafer with bumps, prevents collapse of bumps on the circuit side when grinding the back surface, and prevents generation of dimples or cracks on the grinding surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Base film and pressure-sensitive adhesive sheet provided therewith","description":"The base film of the invention is a base film of a pressure-sensitive adhesive sheet for laminating onto a semiconductor wafer composed of: (A) a layer of a cured product in which a composition includ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9670382","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.
