    Abstract: An image sensor may include a device isolation structure defining a plurality of pixel regions in a substrate and a photoelectric conversion element formed in each of the pixel regions. The device isolation structure may include an insulating gapfill layer extending from an upper portion to a lower portion of the device isolation structure, a spacer provided at the upper portion of the device isolation structure and interposed between the insulating gapfill layer and the substrate, and a lower impurity region provided at the lower portion of the device isolation structure and interposed between the insulating gapfill layer and the substrate.

    Abstract: An image sensor includes a substrate having adjacent pixel regions and respective photodiode regions therein, and a pixel separation portion including a trench extending into the substrate between the adjacent pixel regions. The trench includes a conductive common bias line therein and an insulating device isolation layer between the common bias line and surfaces of the trench. A conductive interconnection is coupled to the common bias line and is configured to provide a negative voltage thereto. Related fabrication methods are also discussed.
