Patent ID: 8786044

Claim:
A photoelectric conversion device comprising: a photoelectric conversion part provided in a semiconductor substrate; a signal generation part configured to generate an electrical signal based on a signal charge generated by the photoelectric conversion part; and a transfer gate configured to transfer a signal charge to the signal generation part from the photoelectric conversion part; and a continuous film configured to cover the photoelectric conversion part, and to cover a top surface of a gate electrode of the transfer gate, wherein a first region is provided between the continuous film and the photoelectric conversion part, the first region being configured to have a refractive index lower than refractive indices of the continuous film and the photoelectric conversion part, and to form an interface boundary with the continuous film, and wherein a second region is provided between the continuous film and the top surface of the gate electrode, the second region being configured to have a refractive index lower than refractive indices of the gate electrode and the continuous film, and to form an interface boundary with the continuous film, and wherein T 2 is greater than T 1 and less than λ/2−T 1 where an optical thickness of the first region is T 1 , an optical thickness of the second region T 2 , and a wavelength of an incident light entering the photoelectric conversion part is λ.
