Abstract
A photoelectric conversion device includes a first substrate including, in a first semiconductor layer, a photoelectric conversion unit and a transfer transistor configured to transfer charges generated in the photoelectric conversion unit, a second substrate including, in a second semiconductor layer, a pixel circuit configured to output a signal based on the charges transferred from the transfer transistor, and a third substrate including, in a third semiconductor layer, a logic circuit configured to process the signal, wherein the first, second and third substrates are stacked in such a way that the second substrate is disposed between the first substrate and the third substrate, wherein the first substrate and the second substrate are electrically connected by a through wiring line penetrating through an insulator included in the second semiconductor layer, and wherein a plane orientation of the first semiconductor layer and a plane orientation of the second semiconductor layer are same.
