There are included a solid-state imaging element, the light-receiving side of which corresponds to one of plate surface sides of a semiconductor substrate; a translucent member provided on the light-receiving side of the solid-state imaging element at a predetermined distance therefrom; and a support portion that forms a cavity between the solid-state imaging element and the translucent member, in which the solid-state imaging element has a layer structure provided on the light-receiving side of the semiconductor substrate, the layer structure including a first layer, a second layer, and a third layer, the second layer being different in material from the first layer, the third layer being different in material from the first layer and formed in the second layer, and the third layer has a protrusion-and-recess shape portion at least in a region where the support portion is formed in a planar direction along the plate surface of the semiconductor substrate, the protrusion-and-recess shape portion forming an interface between the second layer and the third layer in a protrusion-and-recess shape."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state imaging device and solid-state imaging element","description":"To prevent peeling at an interface between layers forming a layer structure of a solid-state imaging element even in a case where stress is caused by an increase in pressure in a cavity in a configura","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11488994","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.
