    摘要: A photo sensing region is included within each pixel in a pixel array. Each photo sensing region collects photo-generated charge. A transfer region is positioned between each photo sensing region and a respective charge coupled device. A charge-coupled device receives charge from each column of pixels in the pixel array. Each charge-coupled device includes one or more barriers for causing the transfer of the charge through the charge-coupled device. Each transfer region includes a barrier that is lower than the one or more barriers in the charge-coupled device so that excess charge in the charge-coupled device flows into the photo sensing region.
