A silicone-based adhesive sheet is disclosed herein, wherein, prior to heating, the delamination mode of the adhesive surface from a non-adhesive substrate is interfacial delamination, and after heating of the adhesive surface in a range of between 50 and 200° C., the delamination mode of the adhesive surface from another non-adhesive substrate changes to cohesive fracturing, and exhibits permanent adhesion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Silicone-based adhesive sheet, multilayer structure including same, and method for producing semiconductor device","description":"Provided is: a layered body wherein a sheet surface has slight adhesiveness, enabling easy temporary securing of a semiconductor chip, or the like, that has been diced, onto a semiconductor substrate,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11939497","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.
