COLOR SOLID-STATE IMAGER AND METHOD OF MAKING THE SAME

摘要

COLOR SOLID-STATE IMAGER AND METHOD OF MAKING THE SAME A color, solid-state imager consists of a semiconductor body over which are successively laminated a predetermined number of filter layers of any desired shape having predetermined spectral characteristics. Laminated on the filter layers is a predetermined number of layers composed of a transparent, organic high molecular material which is sensitive to radiation. The semiconductor substrate has at least a detector portion composed of an array of a plurality of optical detector elements. The method of making such imagers can be simplified by using the radiationsensitive high molecular material for the intermediate layers or protective layers which are used for forming a laminate construction of color-decomposing filters. In mounting the color-separating filters on the semiconductor substrate, it is particularly preferred first to form a film of an organic high molecular material.
