Imaging devices with gated time-of-flight pixels with fast charge transfer

A pixel array includes a plurality of pixels. Each pixel includes a photoelectric conversion region that converts incident light into electric charge, and a charge transfer section coupled to the photoelectric conversion region and having line symmetry along a first axis in a plan view. The charge t...

More Information
Summary:A pixel array includes a plurality of pixels. Each pixel includes a photoelectric conversion region that converts incident light into electric charge, and a charge transfer section coupled to the photoelectric conversion region and having line symmetry along a first axis in a plan view. The charge transfer section includes a first transfer transistor coupled to a first floating diffusion and the photoelectric conversion region and located at a first side of the photoelectric conversion region, and a second transfer transistor coupled to a second floating diffusion and the photoelectric conversion region and located at the first side of the photoelectric conversion region.
