Patent ID: 11482549

Abstract:
A solid-state imaging device includes an imaging element group in which imaging elements each having a photoelectric conversion portion 10 formed on or above a semiconductor substrate 70 and further having a wire grid polarizer 91 and an on-chip microlens 15 are arrayed in a two-dimensional matrix, and a first interlayer insulating layer 83 and a second interlayer insulating layer 84 provided on a light incident side of the photoelectric conversion portions 10. The wire grid polarizer 91 is provided between the first interlayer insulating layer 83 and the second interlayer insulating layer 84, and the on-chip microlens 15 is provided on the second interlayer insulating layer 84. The first interlayer insulating layer 83 and the second interlayer insulating layer 84 include an oxide material or a resin material, and the on-chip microlens includes SiN or SiON.
