Abstract
An image sensor contains a semiconductor substrate, a plurality of pixels defined on the semiconductor substrate, a photo conductive layer and a transparent conductive layer formed on the pixel electrodes of the pixels in order, and a shield device positioned between any two adjacent pixel electrodes. The shield device has a shield electrode and an isolation structure surrounding the shield electrode so that the shield electrode is isolated from the pixel electrodes and the photo conductive layer by the isolation structure.
