Abstract
A photoelectric conversion device includes a first semiconductor substrate including a photoelectric conversion unit for generating a signal charge in accordance with an incident light, and a second semiconductor substrate including a signal processing unit for processing an electrical signal on the basis of the signal charge generated in the photoelectric conversion unit. The signal processing unit is situated in an orthogonal projection area from the photoelectric conversion unit to the second semiconductor substrate. A multilayer film including a plurality of insulator layers is provided between the first semiconductor substrate and the second semiconductor substrate. The thickness of the second semiconductor substrate is smaller than 500 micrometers. The thickness of the second semiconductor substrate is greater than the distance from the second semiconductor substrate and a light-receiving surface of the first semiconductor substrate.
