Abstract
An image sensor includes a pixel array, a dielectric layer, a plurality of first conductive shielding regions, and a plurality of second conductive shielding regions. The pixel array includes photodiodes within a substrate. The dielectric layer is over the substrate. From a plan view, the first conductive shielding regions are adjacent four corners of the pixel array, and the second conductive shielding regions are adjacent four sides of the pixel array. The second conductive region has a length-to-width ratio greater than a length-to-width ratio of the first conductive region.
