Patent abstract
An active pixel includes a a photosensitive element formed in a semiconductor substrate. A transfer transistor is formed between the photosensitive element and a floating diffusion and selectively operative to transfer a signal from the photosensitive element to the floating diffusion. The floating diffusion is formed from an n-type implant with a dosage in the range of 5e13 to 5e14 ions/cm2. Finally, an amplification transistor is controlled by the floating diffusion.
