摘要：
A novel pixel sensor cell structure and method of manufacture. The pixel sensor cell includes a collection well region of a first conductivity type and a pinning layer formed in a substrate. The pinning layer includes a first impurity region of a second conductivity type and a second impurity region of the second conductivity type. The first and second impurity regions can be independently formed to affect multiple parameters of the pixel sensor cell.
