  • Patent number: 8067301
    Abstract: A reliable image sensor and a method for forming the same are provided. The image sensor includes a photo-detective device. At least one transistor is electrically connected to the photo-detective device for outputting charges stored in the photo-detective device. A transistor directly connected to the photo-detective device includes a gate electrode pattern and an ion-implantation interrupting pattern arranged on the gate electrode pattern. Since the ion-implantation interrupting pattern is located on an upper portion of the gate electrode pattern of the transistor in the vicinity of the photo-detective device, a threshold voltage of the gate electrode pattern of the transistor in the vicinity of the photo-detective device is adjusted to a desired value.

    Abstract: A mesh-shaped gate electrode is located over a surface of a substrate. The mesh-shaped gate electrode includes a plurality of first elongate wirings extending parallel to one another, and a plurality of second elongate wirings extending parallel to one another. The first elongate wirings intersect the second elongate wirings to define an array of gate intersection regions over the surface of the substrate and to further define an array of source/drain regions of the substrate. To reduce gate capacitance, at least one oxide region may be located in the substrate below the mesh-shaped gate electrode. For example, an array of oxide regions may be respectively located below the array of gate intersection regions.
