Abstract
A pixel cell for an image sensor including a first semiconductor substrate, a photodiode, and a transfer gate is described. The first semiconductor substrate includes a first side and a second side. The first side is opposite the second side. The photodiode is disposed within the first semiconductor substrate between the first and the second side. The transfer gate is disposed proximate to the first side of the first semiconductor substrate. The transfer gate includes a planar region. The first side of the semiconductor substrate is disposed between the planar region and the photodiode. A lateral area of the photodiode is less than or equal to a lateral area of the planar region of the transfer gate.
