Patent ID: 7592578

Claim:
A method for manufacturing a photoelectric-conversion apparatus that includes: a photoelectric-conversion area having a plurality of photoelectric-conversion elements configured to convert incident light into electrical charges; a plurality of floating-diffusion areas; a plurality of transfer-MOS transistors configured to respectively transfer electrical charges of the plurality of photoelectric-conversion element to the plurality of floating-diffusion areas; a plurality of amplification-MOS transistors each configured to read and transmit a signal generated based on transferred electrical charges to an output line; and an antireflection film provided on a light-receiving surface of each photoelectric-conversion element, wherein the method comprises steps of: forming said antireflection film to cover a light-receiving surface of a photoelectric conversion element, a gate of a corresponding amplification-MOS transistor, and a corresponding floating diffusion area; forming a single contact hole in an area corresponding to the gate of the corresponding amplification-MOS transistor and the corresponding floating diffusion area; etching the antireflection film provided at a base part of the single contact hole; and embedding a conductor in the single contact hole.
