The semiconductor device includes a semiconductor layer having a first main surface and a second main surface opposing the first main surface, a plurality of photodiodes which are formed in the semiconductor layer and in each of which photoelectric conversion is performed, a light receiving lens disposed over the second main surface of the semiconductor layer to supply light to each of the photodiodes, and a mark for alignment formed inside the semiconductor layer. The mark for alignment is formed so as to extend from the first main surface toward the second main surface and have a protruding portion protruding from the second main surface in a direction toward where the light receiving lens is disposed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and manufacturing method thereof","description":"Provided is a semiconductor device which allows an alignment mark used for the manufacturing of a solid-state image sensor (semiconductor device) having a back-side-illumination structure to be formed","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837459","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.
