Claim Text:
1. A photoelectric conversion apparatus, comprising: a plurality of photoelectric conversion portions, each including a first semiconductor region of a first conductivity type; a plurality of charge storage portions, each including a second semiconductor region of the first conductivity type provided at a different position from the first semiconductor region and configured to hold a charge generated by a corresponding one of the plurality of photoelectric conversion portions; a plurality of circuit portions, each including a floating diffusion portion to which a charge of the charge storage portion is transferred and transistors including an amplification transistor configured to output a signal based on a charge transferred to the floating diffusion portion; a first isolation portion including a third semiconductor region of a second conductivity type; a second isolation portion including an insulator; and an active region defined by the second isolation portion, the first semiconductor region included in a first photoelectric conversion portion of the plurality of photoelectric conversion portions and the second semiconductor region included in a first charge storage portion of the plurality of charge storage portions which corresponds to the first photoelectric conversion portion are arranged in a first portion of the active area, the first semiconductor region included in a second photoelectric conversion portion of the plurality of photoelectric conversion portions and the second semiconductor region included in a second charge storage portion of the plurality of charge storage portions which corresponds to the second photoelectric conversion portion are arranged in a second portion of the active area, the first and second portions of the active area are arranged adjacently to each other via the third semiconductor region without the second isolation portion being arranged therebetween, and a part of the second isolation portion is arranged between one of the transistors and the first or second charge storage portion.
