Image sensor having pixels capable of detecting phase differences with each pixel includes dual color filter layer overlapping each other

摘要

An image sensor includes a plurality of pixels arranged in two dimensions, wherein at least one pixel includes: a photoelectric conversion layer formed in a substrate; a first color filter layer formed over the photoelectric conversion layer; and a second color filter layer formed over the first color filter layer and defining an opening that is eccentrically formed with respect to an optical axis of the photoelectric conversion layer.

1. An image sensor, comprising:
a plurality of pixels arranged in two dimensions, wherein at least one pixel includes:
a photoelectric conversion layer formed in a substrate;a first color filter layer formed over the photoelectric conversion layer; anda second color filter layer formed over the first color filter layer, and that defines an opening that is eccentrically formed with respect to an optical axis of the photoelectric conversion layer, wherein an area where the first color filter layer and the second color filter layer overlap with each other is located directly over the photoelectric conversion layer.
