Photoelectric conversion apparatus and imaging system using the photoelectric conversion apparatus

摘要

A photoelectric conversion apparatus of the present invention includes: a plurality of photoelectric conversion elements arranged on a substrate; a transistor for transferring a signal charge; and a plurality of transistors for reading out the signal charge transferred. The plurality of photoelectric conversion elements include a first photoelectric conversion element and a second photoelectric conversion element adjacent to each other. The photoelectric conversion apparatus of the present invention includes: a first semiconductor region having a first conductivity type arranged between the first photoelectric conversion element and the second photoelectric conversion element; and a second semiconductor region having the first conductivity type that is arranged on a region where the plurality of transistors are arranged and that has a width larger than that of the first semiconductor region of the first conductivity type.
