    Abstract: In some embodiments, the present disclosure relates to an integrated chip structure. The integrated chip structure includes a first plurality of interconnects arranged within a first inter-level dielectric (ILD) structure on a first substrate, and a second plurality of interconnects arranged within a second ILD structure between the first ILD structure and a second substrate. A bonding structure is disposed within a recess extending through the second substrate. A connector structure is vertically between the first plurality of interconnects and the second plurality of interconnects. The second plurality of interconnects include a first interconnect directly contacting the bonding structure. The second plurality of interconnects also include one or more extensions extending from directly below the first interconnect to laterally outside of the first interconnect and directly above the connector structure, as viewed along a cross-sectional view.

    Abstract: An image-sensor device includes a substrate including a pixel region and a logic region. A logic transistor is disposed in the logic region and is surrounded by a logic isolation feature. A radiation-sensing region is disposed in the pixel region of the substrate. An epitaxial pixel isolation feature is disposed in the pixel region and surrounds the radiation-sensing region. A doped region with a same doping polarity as the radiation-sensing region is located between a bottom of the radiation-sensing region and the back surface of the substrate. The epitaxial pixel isolation feature is in direct contact with the doped region. The doped region extends continuously under the pixel region and the logic region. The epitaxial pixel isolation feature is in direct contact with the doped region, and the logic isolation feature is spaced apart from the doped region.
