Abstract
Disclosed herein are global shutter image sensors and methods of operating such image sensors. An image sensor includes a semiconductor wafer having a light receiving surface opposite an electrical connection surface; an oxide extending from the light receiving surface toward the electrical connection surface and at least partially surrounding a pixel region; a photodiode disposed within the pixel region; and a set of storage nodes disposed under the photodiode, between the photodiode and the electrical connection surface. The set of storage nodes comprises a first storage node and a second storage node. The storage nodes may be disposed vertically beneath the photodiode, or side by side.
