Abstract: An image sensor is provided. The image sensor includes a substrate, a first interlayer insulating layer, a first metal line, and a shielding structure. The substrate includes a pixel array, a peripheral circuit area, and an interface area disposed between the pixel array and the peripheral circuit area. The first interlayer insulating layer is formed on a first surface of the substrate. The first metal line is disposed on the first interlayer insulating layer of the pixel array. The second interlayer insulating layer is disposed on the first interlayer insulating layer wherein the second interlayer insulating layer covers the first metal line. The shielding structure passes through the substrate in the interface area wherein the shielding structure electrically insulates the pixel array of the substrate and the peripheral circuit area.
