Abstract
An image sensor device includes a substrate, a deep-trench isolation structure, an oxide layer, a light blocking structure, and an adhesion layer. The substrate has a photosensitive region. The deep-trench isolation structure is in the substrate and adjacent the photosensitive region. The oxide layer is over the photosensitive region and the deep-trench isolation structure. The light blocking structure is over the oxide layer. A bottom portion of the light blocking structure is embedded in the oxide layer. The adhesion layer is between the light blocking structure and the oxide layer. The adhesion layer extends beyond a sidewall of a top portion of the light blocking structure.
