Abstract
A solid state image sensor according to an embodiment includes a transfer gate, a floating diffusion portion that converts signal charge transferred from a photodiode via the transfer gate into a voltage signal, and an extraction electrode that is formed of a film of conductive material including any of amorphous silicon, monocrystalline silicon, or N+ polysilicon, that has a peripheral edge portion surrounded by a film of insulating material and one end electrically connected to the floating diffusion portion, and that transmits the voltage signal.
