Document Type and Number:
WIPO Patent Application WO/2022/196383
Kind Code:
A1
Abstract:
Provided is an image capturing device configured such that color mixing between pixels can be reduced. An image capturing device according to the present invention is provided with: a first semiconductor substrate including a plurality of photoelectric conversion elements; a lens body provided on the side of one face of the first semiconductor substrate; and a wiring layer provided on the reverse side of the one face of the first semiconductor substrate. The first semiconductor substrate includes an element separating section disposed between one photoelectric conversion element and the other photoelectric conversion element adjacent to each other among the plurality of photoelectric conversion elements. The wiring layer includes a first separating section disposed at a position facing the element separating section. The first separating section includes a first low-refractive-index region and a first high-refractive-index region abutting the first low-refractive-index region. The first high-refractive-index region sandwiches the first low-refractive-index region from both sides.
