Abstract
A barrier for isolating the dark correction pixels from spurious charges within an image sensor. The barrier comprises a charge absorbing region in a substrate electrically connected to a voltage source terminal. The charge absorbing region completely surrounds the dark correction region of a pixel array. The charge absorbing region absorbs carriers generated by lateral diffusion, near-infrared and infrared light reflected from the bottom of the silicon substrate, and other sources. This absorbing region prevents carriers from being absorbed into the dark correction pixel cells and causing image correction distorting effects.
