ABSTRACT:
A pixel cell has controlled photosensor anti-blooming leakage by having dual pinned voltage regions, one of which is used to set the anti-blooming characteristics of the photosensor. Additional exemplary embodiments also employ an anti-blooming transistor in conjunction with the dual pinned photosensor. Other exemplary embodiments provide a pixel with two pinned voltage regions and two anti-blooming transistors. Methods of fabricating the exemplary pixel cells are also disclosed.
