Abstract:
An exemplary embodiment is a photoelectric conversion device having a photoelectric conversion portion, and a transfer portion. The transfer portion transfers charges of the photoelectric conversion portion. The photoelectric conversion portion includes first and second semiconductor regions of a first conductivity type. Charges generated by photoelectric conversion are accumulated in the first and second semiconductor regions. According to the structure of the first and second semiconductor regions of the exemplary embodiment or the method for manufacturing them, the transfer efficiency of charges can be improved while improving the sensitivity of the photoelectric conversion portion.
