ABSTRACT:
On the surface of a protecting layer mounted on a solid state imaging devices substrate, transparent gap filler layers and a transparent flattening layer are formed to flatten a surface of overlying protecting layer. On a surface of the transparent flattening layer, color filters of red, blue and yellow are formed. The color filters are made of synthetic photosensitive material. By using the synthetic photosensitive material, the color filters are formed with good shape and precision. All of the color filter show good photo spectrography and uniform characteristics. For the reasons, excellent characteristics of the solid state imaging device are provided which are free form image inferiority caused by flicker, shading, dust and so forth.
