Solid-state image capturing apparatus, method for manufacturing same, and electronic information device

A solid-state image capturing apparatus, comprising:

• a plurality of photoelectric conversion sections for generating a signal charge by a photoelectric conversion on incident light;
• a charge accumulation section for accumulating the signal charge generated by each of the photoelectric conversion section;
• and
• a charge readout section for reading out the signal charge from each of the photoelectric conversion sections to the charge accumulation section, the solid-state image capturing apparatus further comprising:
• a semiconductor substrate including a plurality of diffusion layers formed thereabove, the diffusion layers constituting the photoelectric conversion sections, the charge accumulation section and the charge readout section;
• a readout gate electrode formed above the semiconductor substrate and constituting the charge readout section;
• an insulation sidewall formed on a side surface of the readout gate electrode;
• and
• a surface diffusion layer constituting the photoelectric conversion sections, the surface diffusion layer being positioned in a self-aligning manner with respect to the readout gate electrode by the insulation sidewall.
