    Abstract: A method for fabricating an image-sensor device is provided. The method includes forming a radiation-sensing region and a doped isolation region in a semiconductor substrate. The doped isolation region is adjacent to the radiation-sensing region. The method also includes thinning the semiconductor substrate such that the radiation-sensing region and the doped isolation region are exposed. The method further includes partially removing the doped isolation region to form a recess. In addition, the method includes forming a negatively charged film over an interior surface of the recess and a surface of the radiation-sensing exposed after the thinning of the semiconductor substrate.

    Abstract: Various embodiments of the present disclosure are directed towards an image sensor. The image sensor includes a photodetector disposed in a semiconductor substrate. An interlayer dielectric (ILD) structure is disposed on a first side of the semiconductor substrate. A storage node is disposed in the semiconductor substrate and spaced from the photodetector, where the storage node is spaced from the first side by a first distance. A first isolation structure is disposed in the semiconductor substrate and between the photodetector and the storage node, where the first isolation structure extends into the semiconductor substrate from a second side of the semiconductor substrate that is opposite the first side, and where the first isolation structure is spaced from the first side by a second distance that is less than the first distance.
