Solid-state imaging device, electronic apparatus, and mobile body

An electronic apparatus comprising a solid-state imaging device, wherein

• the solid-state imaging device includes
• a semiconductor layer stacked on a first Si substrate, and including a photoelectric conversion region that has a predetermined wavelength selectivity and a floating diffusion region that converts electric charge transferred from the photoelectric conversion region into an electric signal and outputs the electric signal,
• a first capacitor section formed in the first Si substrate, and holding a reset voltage of the floating diffusion region at a time when a voltage of the floating diffusion region is reset, and
• a second capacitor section formed in the first Si substrate, and holding a signal voltage generated by the electric signal.

A mobile body comprising a solid-state imaging device, wherein

• the solid-state imaging device includes
• a semiconductor layer stacked on a first Si substrate, and including a photoelectric conversion region that has a predetermined wavelength selectivity and a floating diffusion region that converts electric charge transferred from the photoelectric conversion region into an electric signal and outputs the electric signal,
• a first capacitor section formed in the first Si substrate, and holding a reset voltage of the floating diffusion region at a time when a voltage of the floating diffusion region is reset, and
• a second capacitor section formed in the first Si substrate, and holding a signal voltage generated by the electric signal.
