US Patent 11004884 Solid-state imaging apparatus

An imaging device includes one or more insulating layers on a substrate; an effective region including: a polarization layer in the one or more insulating layers and including one or more polarizers that polarize light; and at least one first photoelectric conversion region in the substrate and that converts incident light polarized by the one or more polarizers into electric charge; and a peripheral region outside the effective region and including: one or more wiring layers that include a pad portion in a same layer of the one or more insulating layers as the polarization layer.
