CMOS image sensor having global shutter pixels built using a buried channel transfer gate with a surface channel dark current drain

The invention describes a solid-state CMOS image sensor array and in particular describes in detail image sensor array pixels having global and rolling shutter capabilities that are using a dual channel transfer-storage gate for charge transfer from a PD to a TX gate well and from the TX gate well onto a FD. The dual channels are stacked above each other where a shallow charge channel is used to drain surface generated dark current away from the pixel structure, while a buried bulk channel provides for standard charge transfer and storage functions. This feature thus improves the sensor noise performance and prevents signal contamination and various shading effects caused by the dark current buildup during a prolonged charge storage sequence in pixels of image sensor arrays using the global shutter mode of operation. Several embodiment of this concept are described including pixels which utilize shared circuitry, a complete PD reset capability, and an efficient anti-blooming control.
