Abstract
Disclosed herein are image apparatuses comprising a frontside surface, a backside surface, a storage region (e.g., a storage node or a floating diffusion node), the storage region being situated closer to the frontside surface than to the backside surface, a storage well situated between the backside surface and the storage region, and a doping region situated between the storage region and the storage well. An impurity type of the doping region is opposite an impurity type of the storage well. A lateral area of the storage well is greater than or equal to a lateral area of the storage region, and no portion of a lateral perimeter of the storage region extends outside of a lateral perimeter of the storage well.
