Abstract
A solid-state image sensor is provided. The solid-state image sensor includes a plurality of photoelectric conversion elements. The solid-state image sensor also includes a modulation layer disposed above the photoelectric conversion elements, and the modulation layer has a plurality of modulation segments. The modulation layer includes a plurality of first sub-layers and a plurality of second sub-layers having different refractive indexes. From the top view of the modulation layer, the modulation segments form a first group and a second group, and the second group is adjacent to the first group. The arrangement of the first sub-layers and the second sub-layers in the first group is different from the arrangement of the first sub-layers and the second sub-layers in the second group.
