Abstract
An image sensor includes: a pixel array including a plurality of photodiodes arranged on an upper surface of a substrate, pixel isolation layers extending from the upper surface to a lower surface of the substrate and disposed between the plurality of photodiodes, and pixel circuits. The pixel array includes pixel groups respectively including two or more of the photodiodes, at least one color filter, and at least one microlens. The at least one color filter included in each of the pixel groups has one color, and the pixel isolation layers includes a first pixel isolation layer disposed between the pixel groups and containing silicon oxide and polysilicon; and a second pixel isolation layer containing silicon oxide and extending in a first direction and a second direction, which intersect each other between the two or more photodiodes in each of the pixel groups.
