    Abstract: Image sensors and methods of manufacturing image sensors are provided. One such method includes forming a structure that includes a semiconductor layer extending from a front side to a back side, and a capacitive insulation wall extending through the semiconductor layer. The capacitive insulation wall includes first and second insulating walls separated by a region of a conductor or a semiconductor material. Portions of the semiconductor layer and the region of the conductor or semiconductor material are selectively etched, and the first and second insulating walls have portions protruding outwardly beyond a back side of the semiconductor layer and of the region of the conductor or semiconductor material. A dielectric passivation layer is deposited on the back side of the structure, and portions of the dielectric passivation layer are locally removed on a back side of the protruding portions of the first and second insulating walls.

    Abstract: Image sensors and methods of manufacturing image sensors are provided herein. In an embodiment, a method of manufacturing an image sensor includes forming a structure having a front side and a back side. The structure includes a semiconductor layer extending between the front side and the back side of the structure, and a capacitive insulation wall extending through the semiconductor layer between the front side and the back side of the structure. The capacitive insulation wall includes first and second insulating walls separated by a region of a conductive or semiconductor material. The method further includes selectively etching, from the back side of the structure, portions of the semiconductor layer and the region of conductive or semiconductor material, while retaining adjacent portions of the first and second insulating walls.

    Abstract: An integrated circuit includes an UTBOX insulating layer under and plumb with first and second electronic components, and corresponding ground planes and oppositely-doped wells made plumb with them. The wells contact with corresponding ground planes. A pair of oppositely doped bias electrodes, suitable for connecting corresponding bias voltages, contacts respective wells and ground planes. A third electrode contacts the first well. A first trench isolates one bias electrode from the third electrode and extends through the layer and into the first well. A second trench isolates the first bias electrode from one component. This trench has an extent that falls short of reaching an interface between the first ground plane and the first well.
