The first and second substrates are bonded together such that the first wiring layer and the second semiconductor substrate are opposed to each other. The device includes a first coupling structure for electrically coupling a circuit of the first substrate and the circuit of the second substrate. The first coupling structure includes a via in which electrically-conductive materials are embedded in a first through hole that exposes a wiring line in the first wiring layer and in a second through hole that exposes a wiring line in the second wiring layer or a film-formed structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state imaging device with multiple substrates","description":"A solid-state imaging device including: a first substrate having a pixel unit, and a first semiconductor substrate and a first wiring layer; a second substrate with a circuit, and a second semiconduct","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11476294","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.
