Abstract
An image sensor structure is provided. The image sensor structure includes a substrate including a first light sensing region and a second light sensing region. The image sensor structure further includes an isolation structure formed through the substrate to separate the first light sensing region and the second light sensing region and a first source/drain structure and a second source/drain structure formed at a front side of the substrate. In addition, the first source/drain structure and the second source/drain structure are located at opposite sides of the isolation structure. The image sensor structure further includes a contact formed over the isolation structure, a portion of the first source/drain structure, and a portion of the second source/drain structure.
