Abstract
An image sensor includes a first sensing unit. The first sensing unit includes a pair of photodiodes formed in a substrate and spaced by a deep trench isolation structure, an outer grid over the pair of photodiodes, a color filter filled in the outer grid, and an inner grid disposed in the color filter. The color filter overlaps the pair of photodiodes. The inner grid includes a first spacer, wherein the first spacer is rotated relative to the deep trench isolation structure.
