Patent abstract
An active pixel using a photodiode with multiple species of P type dopants is disclosed. The pixel comprises a photodiode formed in a semiconductor substrate. The photodiode is a P− region formed within an N-type region. The P− region is formed from an implant of boron and an implant of indium. Further, the pixel includes a transfer transistor formed between the photodiode and a floating node and selectively operative to transfer a signal from the photodiode to the floating node. Finally, the pixel includes an amplification transistor controlled by the floating node.
