Title: IMAGE-CAPTURE ELEMENT AND METHOD FOR MANUFACTURING IMAGE-CAPTURE ELEMENT
Abstract:
Provided is an image-capture element provided with: a first conductivity-type substrate (10); a first conductivity-type element forming portion (20) provided on the substrate and having a lower concentration than the substrate; and a plurality of two-dimensionally arranged pixel portions (30) which are provided in the element forming portion and each of which includes a light reception element (32) and a second conductivity-type carrier absorbing portion (80) provided in a different region from the light reception element. Among the plurality of pixel portions, at least one pixel portion includes, on the substrate side with respect to the light reception element: a first conductivity-type first wall portion (41) having a higher concentration than the substrate and disposed so as to overlap at least one of the light reception elements in a direction in which the plurality of pixel portions are arranged; and a carrier passing area (Rcp) in which the first wall portion is not provided in the direction in which the plurality of pixel portions are arranged.
