Abstract:
1. A photoelectric conversion device comprising: a plurality of photoelectric conversion units, each having a plurality of photoelectric conversion elements on which light condensed by one microlens is incident; wherein each of the plurality of photoelectric conversion elements includes a first semiconductor region of a first conductivity type for collecting a signal charge, wherein a height of a potential barrier with respect to a signal charge of at least a portion of a region between the first semiconductor regions of the photoelectric conversion elements arranged adjacent to each other and included in a one photoelectric conversion unit is lower than a height of a potential barrier arranged between the first semiconductor regions of the photoelectric conversion elements arranged adjacent to each other and each included in different photoelectric conversion units arranged adjacent to each other, and wherein each microlens is disposed to overlap a plurality of the first semiconductor regions contained in one pixel with respect to a planar view of the photoelectric conversion unit, and condenses light on the plurality of the first semiconductor regions.
