Abstract
Image sensor structures are provided. The image sensor structure includes a substrate and a light-sensing region formed in the substrate. The image sensor structure further includes a first isolation structure surrounding the light sensing region and having an opening region in a top view and a second isolation structure formed in the substrate. In addition, the second isolation structure surrounds the light-sensing region and vertically overlaps both the opening region and the first isolation structure. The image sensor structure further includes a first gate structure formed over the substrate and overlapping the opening region, the first isolation structure, and the second isolation structure.
