  • Patent number: 7259789
    Abstract: A method of producing a color filter composed of filter elements of RGB is used for a solid-state imaging device, which color filter is capable of improving the resolution of the device. The method includes the steps of: forming a filter layer of a second color in a region in which a filter element of a first color is to be formed; and stacking a filter layer of a third color different from the second color on the filter layer of the second color. In the method, the color filter is preferably composed of filter elements of a plurality of the first colors each of which is either of red, green and blue colors.
