Abstract: A photoelectric conversion apparatus includes pixels having adjacent first and second pixels. The pixels each include, in a semiconductor layer of a substrate, a photoelectric conversion portion that generates charges, a charge holding portion that holds the charges, and a floating diffusion layer that converts the charges into a voltage. At least parts of the charge holding portion in the first pixel and the floating diffusion layer in the second pixel, parts of the charge holding portion in the first pixel and the charge holding portion in the second pixel, and/or parts of the floating diffusion layer in the first pixel and the floating diffusion layer in the second pixel overlap each other without physically touching each other in a depth direction of the substrate in a state where a region for separating the at least parts of the charge holding portions and the floating diffusion layers is provided therebetween.

Abstract: A solid-state imaging device includes pixels forming pixel rows, and a scanning circuit that performs a reset operation of a photoelectric converter and a readout operation of a pixel signal based on charges generated by the photoelectric converter including charge transfer from the photoelectric converter to the holding unit. The pixel rows include imaging rows and focus detection rows. The scanning circuit performs an image capture scan of the imaging rows and a focus detection scan of the focus detection rows, independently, such that signals of the focus detection rows are output after signals from the imaging rows. The scanning circuit performs the focus detection scan such that the reset operation on the focus detection row does not overlap with a charge transfer period on an imaging row belonging to a unit pixel row neighboring a unit pixel row to which a focus detection row under the reset operation belongs.
