Abstract:
A pixel, is provided the pixel comprising: a photodiode structure built on top of an integrated circuit generating a charge; the integrated circuit comprising at least one semiconductor material and at least one interconnect layer; the at least one interconnect layer comprises an interconnect to facilitate charge flowing into a collection node disposed in the semiconductor material; the interconnect being in contact with a doped contact diffusion disposed proximate to the collection node; a transfer transistor disposed between the collection node and a conversion node, the conversion node coupled to an active transistor; the pixel having a reset configured to reset the conversion node.
