Patent ID: 11329079

Abstract:
An imaging device including a semiconductor substrate; a photoelectric converter stacked on the semiconductor substrate, the photoelectric converter being configured to generate a signal through photoelectric conversion of incident light; a multilayer wiring structure located between the semiconductor substrate and the photoelectric converter; and circuitry located in the multilayer wiring structure and the semiconductor substrate, the circuitry being configured to detect the signal. The circuitry includes a first capacitance element and a second capacitance element; and a first transistor including a first source and a first drain in the semiconductor substrate and a first gate. The first capacitance element includes a first electrode, a second electrode, and a dielectric film between the first electrode and the second electrode, the multilayer wiring structure includes an insulating layer adjacent to the first capacitance element, and a permittivity of the dielectric film is greater than a permittivity of the insulating layer.
