More Information
Summary:A photoelectric conversion apparatus including: a first component including a first substrate (FS) having a first plane and a pixel region in which avalanche photodiodes are arranged, and a first wiring layer provided on a side where the first plane of the FS is provided; and a second component including a second substrate (SS), a quenching device, and a second wiring layer, the SS having a third plane, the second wiring layer being provided on a side where the third plane of the SS is provided. The SS has an insulating region, and the insulating region has a through-electrode provided in a through-region that penetrates through the SS. The quenching device is separated from another element by the insulating region. The first component and the second component are electrically connected to each other in a region that overlaps the pixel region in a plan view.
