ABSTRACT:
An object of the present invention is to provide a small solid-state image sensor which realizes significant improvement in sensitivity. The solid-state image sensor of the present invention includes a semiconductor substrate in which photoelectric conversion units are formed, a light-blocking film which is formed above the semiconductor substrate and has apertures formed so as to be positioned above respective photoelectric conversion units, and a high refractive index layer formed in the apertures. Here, each aperture has a smaller aperture width than a maximum wavelength in a wavelength of light in a vacuum converted from a wavelength of the light entering the photoelectric conversion unit through the apertures, and the high refractive index is made of a high refractive index material having a refractive index which allows transmission of light having the maximum wavelength through the aperture.
