摘要： 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.

摘要： An image sensor includes a first pixel array. The first pixel array includes multiple photo diodes and a polyhedron structure. The polyhedron structure is located above the photo diodes, and the polyhedron structure includes a bottom facet, a top facet, and at least one side facet. The bottom facet is located between the side facet and the photo diodes, and an orthogonal projection of the polyhedron structure overlaps with photo diodes. The polyhedron structure is configured to divide an incident light into a plurality of light beams focused in the photo diodes.
