Abstract
An image sensor device is provided. The image sensor device includes a semiconductor substrate having a first light-sensing region and a second light-sensing region adjacent to the first light-sensing region. The image sensor device includes an isolation structure in the semiconductor substrate and surrounding the first light-sensing region and the second light-sensing region. The image sensor device includes a reflective grid over the isolation structure and surrounding the first light-sensing region and the second light-sensing region. The image sensor device includes a first color filter over the first light-sensing region and extending into a first trench of the reflective grid. The image sensor device includes a second color filter over the second light-sensing region and extending into the first trench to be in direct contact with the first color filter in the first trench.
