Abstract
A pixel cell has a photodiode, a readout circuit, and a vertical transfer transistor. The photodiode is disposed within a first substrate of a first semiconductor chip for accumulating an image charge in response to light incident upon the photodiode. The readout circuit is disposed within a second substrate of a second semiconductor chip. The vertical transfer transistor is coupled between the photodiode and the readout circuitry to transfer the image charge from the photodiode to the readout circuitry.
