A device structure is formed in a first section of the handle wafer, and a second section of the handle wafer adjoining the first section of the handle wafer is removed to expose a surface of the buried dielectric layer of the silicon-on-insulator substrate. A permanent substrate is attached to the surface of the buried dielectric layer. When the permanent substrate is attached to the surface of the buried dielectric layer, the section of the handle wafer is received inside a cavity defined in the permanent substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device layer transfer with a preserved handle wafer section","description":"Assemblies including a device layer of a silicon-on-insulator (SOI) substrate and a replacement substrate replacing a handle wafer of the SOI substrate, and methods for transferring the device layer o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9818637","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.
