Title:
SOLID-STATE IMAGING DEVICE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/038999
Kind Code:
A1
Abstract:
The objective of the invention is to reduce reflected light in a solid-state imaging device equipped with a polarization element without influencing the properties of the polarization element. The solid-state imaging device has a plurality of pixels. Each of the plurality of pixels has a photoelectric conversion element performing photoelectric conversion, and a polarization element provided on the light inlet side of the photoelectric conversion element. In addition, the solid-state imaging device has a photo-absorption layer. The photo-absorption layer is formed in inter-pixel regions among the plurality of pixels, to a higher position than the height of the polarization element in the pixels. Accordingly, the photo-absorption layer absorbs reflected light generated in the polarization element.
