ABSTRACT:
A method and system for preventing white pixel difficulties resulting from undesired current induced in an image sensor having a photodiode and a depletion region therein. The photodiode is isolated in a pixel layout for an image sensor. A depletion region is configured, such that the depletion region is maintained in a defect-free region associated with the pixel layout for the image sensor, thereby reducing white pixel difficulties caused by induced and undesired current. The image sensor is preferably a CMOS image sensor. A depletion region of the photodiode is constantly maintained in a defect-free region during operation of the CMOS image sensor.
