ABSTRACT:
A method and structure for reducing dark current in an image sensor includes preventing unwanted electrons from being collected in the photosensitive region of the image sensor. In one embodiment, dark current is reduced by providing a deep n-type region having an n-type peripheral sidewall formed in a p-type substrate region underlying a pixel array region to separate the pixel array region from a peripheral circuitry region of the image sensor. The method and structure also provide improved protection from blooming.
