Abstract
To increase the capacity of a charge holding section of a pixel in an imaging device that performs imaging using a global shutter method. An imaging device includes a photoelectric converter, a first charge holding section, an auxiliary charge holding section, a transfer route, and an image signal generator. The first charge holding section is formed near a front surface of a semiconductor substrate. A first charge transfer section transfers charge from the photoelectric converter to the first charge holding section. The auxiliary charge holding section underlies the first charge holding section, and holds a portion of the charges held in the first charge holding section. The transfer route transfers the charge between the first charge holding section and the auxiliary charge holding section. The image signal generator generates an image signal based on the charges held in the first charge holding section and the auxiliary charge holding section.
