Abstract
An imaging pixel may be provided with a photodiode and a floating diffusion region. The pixel may include at least one storage capacitor that can store charge from the floating diffusion region. The at least one storage capacitor may provide global shutter functionality for the pixel. Multiple storage capacitors may be provided for correlated double sampling (CDS) techniques and high dynamic range (HDR) images. The imaging pixel may have an upper substrate layer and a lower substrate layer. The photodiode may be formed in the upper substrate layer, and the storage capacitors may be formed in the lower substrate layer. A interconnect layer may couple pixel circuitry in the upper substrate layer to pixel circuitry in the lower substrate layer.
