Imaging method, apparatus, and system providing improved imager quantum efficiency |
摘要 |
A method, apparatus, and system that provides one or more charge collecting protection regions in a pixel array, each formed below a storage region of a pixel cell, but not below at least one photosensor of one pixel of the array. The storage region includes a floating diffusion region and/or a storage gate in the pixel cell of the imaging device. The protection regions can keep stray charges from reaching the storage regions.
