Abstract
An image sensor includes a photosensitive region disposed within a semiconductor layer and a stress adjusting layer. The photosensitive region is sensitive to light incident through a first side of the image sensor to collect an image charge. The stress adjusting layer is disposed over the first side of the semiconductor layer to establish a stress characteristic that encourages photo-generated charge carriers to migrate towards the photosensitive region.
