Abstract
A multicolor solid image pickup element having bonding pat portions is prepared by an on-wafer method utilizing a silver halide photographic emulsion. A solvent permeating preventing layer is formed on a solid image pickup element base plate having an array of image elements. A silver halide emulsion layer is then formed in the layer, and the emulsion layer is removed at the portions corresponding to the bonding pat portions of the base plate. A micro color filter composed of two or more color separation filter elements is then formed in the emulsion layer by applying thereto a repeating pattern exposure, followed by color development. Each of the color filter elements corresponds to each image element, and a protective layer is formed on the whole surface of the base plate. The protective layer and the solvent permeation preventing layer are then successively removed at the portions corresponding to the bonding pat portions.
