Abstract
An image sensor includes a pixel and an isolation structure. The pixel includes a photosensitive region and a circuitry region next to the photosensitive region. The isolation structure is located over the pixel, where the isolation structure includes a conductive grid and a dielectric structure covering a sidewall of the conductive grid, and the isolation structure includes an opening or recess overlapping the photosensitive region. The isolation structure surrounds a peripheral region of the photosensitive region.
