Title:
IMAGING ELEMENT AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/149349
Kind Code:
A1
Abstract:
According to the present invention, any reduction in the sensitivity of a pixel provided with a charge holding part is prevented. An imaging element comprises photoelectric conversion parts, separation parts, and an image signal generation unit. Each of the photoelectric conversion parts is positioned on a semiconductor substrate and performs photoelectric conversion of incident light from a subject. The separation parts are adjacent to the photoelectric conversion parts and are configured in a wall shape inclined obliquely from a light-receiving surface, which is a surface of the semiconductor substrate that is irradiated with the incident light, toward the photoelectric conversion parts, the separation parts separating the photoelectric conversion parts. The image signal generation unit generates an image signal based on the photoelectric conversion.
