ABSTRACT:
Quantum efficiency in an active pixel sensor improved by proper sizing and shaping of the contacts. The photodiode elements are formed of special shapes that are optimized for obtaining diffusion of charge, rather than obtaining the charge directly. Photogates are formed with a thinned polysilicon covering.
