Abstract
An image sensor may include a plurality of light-gathering pixels and a plurality of substrates. The pixels may each comprise at least one photodiode, a floating diffusion node, and a pixel readout circuit. The pixel readout circuit may include a plurality of transistors, which may be controlled to transfer electrical charge out of the photodiode through the floating diffusion node to generate an analog signal at an output. The pixels may be formed or fabricated on or within the substrates such that for each pixel, a first substrate may include the photodiode, floating diffusion node, and a first subset of the transistors of the pixel readout circuit that is electrically connected with the floating diffusion node directly, and one or more other substrates may include at a second subset of the transistors that is electrically connected with the floating diffusion node indirectly.
