Abstract
According to a solid-state imager of this invention, in case where a plurality of color filters are disposed on a semiconductor body for the solid-state imager including a plurality of photosensitive regions and where the color filter of a third color is constructed by the overlapping between filter members of a first color and a second color, that one of the filter members which has a spectral transmittance substantially transmitting light for exposure for use in forming the filter members is arranged as a lower layer closer to a substrate of the semiconductor body. Even when the filter members are formed by the exposure process, a solid-state imager having good characteristics can be manufactured.
