Abstract: In one embodiment, an integrated image sensor includes an array of pixels in which each pixel includes a photosensitive area configured to integrate a luminous signal by generating electron-hole pairs so as to form a first signal representative of the number of electrons in the generated electron-hole pairs and a second signal representative of the number of holes in the generated electron-hole pairs. A first circuit portion is configured to store the first signal sheltered from light. A second circuit portion is configured to store the second signal sheltered from light. A third circuit portion is configured to read the first signal and the second signal and able to perform combination operations between the first signal and the second signal so as to generate a combined signal representative of an image, where the integrated image sensor is tailored to operate in a global shutter control mode.

Abstract: An image sensor device may include an array of image sensing pixels arranged in rows and columns. Each image sensing pixel may include an image sensing photodiode, a first source follower transistor coupled to the image sensing photodiode, and a switch coupled to the image sensing photodiode. Each image sensor device may include a second source follower transistor coupled to the switch, and a row selection transistor coupled to the first and second source follower transistors.

Abstract: A photodiode produces photogenerated charges in response to exposure to light. An integration period collects the photogenerated charges. Collected photogenerated charges in excess of an overflow threshold are passed to an overflow sense node. Remaining collected photogenerated charges are passed to a sense node. A first signal representing the overflow photogenerated charges is read from the overflow sense node. A second signal representing the remaining photogenerated charges is read from the sense node.

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.
