Each photosensitive region is laterally framed by a respective vertical annular gate. The vertical annular gates are biased by a control circuit during an integration phase so as to generate an electrostatic potential comprising potential wells in the central portion of the volume of each doped photosensitive region and a potential barrier at each interface between two neighboring doped photosensitive regions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image sensor intended to be illuminated via a back side, and corresponding method for acquiring a light flux","description":"A back side illuminated image sensor includes a pixel formed by three doped photosensitive regions that are superposed vertically in a semiconductor substrate.
