Abstract: An imaging device includes: a first pixel array including a first photoelectric converter and first pixel electrodes connected to the first photoelectric converter; and a second pixel array including a second photoelectric converter and second pixel electrodes connected to the second photoelectric converter. The first pixel array and the second pixel array are stacked one on another. In a plan view, an area of an overlapping region defined by overlapping between the first pixel electrodes and a corresponding second pixel electrode of the second pixel electrodes is smaller than an area of a remaining region obtained by excluding the overlapping region from the corresponding second pixel electrode.

Abstract: An imaging device includes a semiconductor substrate and pixels. Each of the pixels includes a first capacitive element including a first electrode provided above the semiconductor substrate, a second electrode provided above the semiconductor substrate, and a dielectric layer located between the first electrode and the second electrode. At least one selected from the group consisting of the first electrode and the second electrode has a first electrical contact point electrically connected to a first electrical element and a second electrical contact point electrically connected to a second electrical element different from the first electrical element. The first capacitive element includes at least one trench portion having a trench shape.

Abstract: An imaging device includes a first pixel and a second pixel adjacent to the first pixel. Each of the first pixel and the second pixel includes a first electrode, a second electrode positioned on or above the first electrode and facing the first electrode, a photoelectric conversion layer positioned between the first electrode and the second electrode, and a first charge-blocking layer positioned between the first electrode and the photoelectric conversion layer. The first charge-blocking layer of the first pixel is separated from the first charge-blocking layer of the second pixel. The photoelectric conversion layer is disposed continuously to the first pixel and the second pixel. An area of the first charge-blocking layer of the first pixel is larger than an area of the first electrode of the first pixel in plan view.

Abstract: An image sensor includes pixel electrodes, a control electrode, a photoelectric conversion film arranged on the pixel electrodes, a transparent electrode arranged on the photoelectric conversion film, an insulating layer arranged on at least a portion of a top surface of the transparent electrode, and a connection layer that electrically connects the control electrode to the transparent electrode. The connection layer is in contact with at least one side surface of the transparent electrode. A side surface of the insulating layer, the at least one side surface of the transparent electrode, and a side surface of the photoelectric conversion film are aligned with each other.
