Patent ID: 7867810

Claim:
A method for manufacturing a solid-state image capturing apparatus including a pixel array constituted of a plurality of pixels, wherein each of the plurality of pixels includes a photoelectric conversion section, the method comprising the steps of: forming an impurity diffusion area in a surface area of a semiconductor substrate, wherein the impurity diffusion area constitutes the photoelectric conversion section; and forming a plurality of different impurity diffusion areas in the surface area of the semiconductor substrate, other than the impurity diffusion area constituting the photoelectric conversion section, wherein the step of forming the impurity diffusion area constituting the photoelectric conversion section includes a step of forming a resist mask for preventing implantation of an impurity in the surface area of the semiconductor substrate by the exposure and development of a resist material that includes a photo-acid-generating agent, and wherein the resist material is obtained by replacing at least a portion of iodonium salt contained in a chemical amplification type resist with a photo-acid-generating agent which does not contain iodine in order to reduce white defects, wherein the chemical amplification type resist contains iodonium salt content as the photo-acid-generating agent, wherein the iodonium salt content is determined based on at least a wavelength of an exposure light and a film thickness of the resist mask.
