Abstract
According to some embodiments, an image sensor pixel includes a floating diffusion, a transistor gate configured to transfer charge with respect to the floating diffusion, and a doped pinning region disposed between the floating diffusion and the transistor gate, to reduce or eliminate the effective capacitive coupling between the floating diffusion and the transistor gate. The transistor gate may be an in-pixel transfer gate configured to selectively transfer photocharge from an in-pixel charge accumulation region to the floating diffusion. Alternatively, or additionally, the transistor gate may be an in-pixel reset gate configured to selectively reset the electrostatic potential of the floating diffusion.
