Abstract
A color solid-state imager comprises a semiconductor body over which are successively laminated a predetermined number of filter layers of any desired shape having predetermined spectral characteristics and, laminated on the filter layers, a predetermined number of layers composed of a transparent, organic high molecular material which is sensitive to radiation, the semiconductor substrate having at least a detector portion composed of an array of a plurality of optical detector elements. The method of making color solid-state imagers can be simplified by at least using the radiation-sensitive high molecular material for the intermediate layers or protection layers which are used for forming a laminate construction of color-decomposing filters. Further, in mounting the color-decomposing filters on the semiconductor substrate, it is particularly preferred to form beforehand a film of an organic high molecular material.
