IMAGE PICKUP APPARATUS AND IMAGE PICKUP SYSTEM |
摘要 |
In a photoelectric conversion apparatus that adds signals of a plurality of photoelectric conversion elements included in photoelectric conversion units, each of the plurality of photoelectric conversion elements includes a first semiconductor region of a first conductivity type that collects signal carriers. The first semiconductor regions included in photoelectric conversion elements that are included in each of the photoelectric conversion units and that are arranged adjacent to each other sandwich a second semiconductor region of a second conductivity type. A height of a potential barrier for the signal carriers generated in a certain region of the second semiconductor region is smaller than a height of a potential barrier for the signal carriers generated in a third semiconductor region between each of the first semiconductor regions and an overflow drain region of the first conductivity type.
