Title:
SOLID-STATE IMAGING DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/100447
Kind Code:
A1
Abstract:
Provided is a solid-state imaging device with which it is possible to further improve image quality and function. Provided is a solid-state imaging device including a pixel region in which a plurality of pixels are arranged two-dimensionally. The pixels have: a photoelectric conversion unit for photoelectrically converting incident light, the photoelectric conversion unit being formed on a semiconductor substrate; and a concave-convex part formed in a region above the photoelectric conversion unit and on the light reception surface-side of the semiconductor substrate. The number of concave-convex features on the concave-convex part of the pixels positioned at the center part of the pixel region and the number of concave-convex features on the concave-convex part of the pixels positioned at the peripheral part of the pixel region are different.
