Abstract
A method for producing a low capacitance floating diffusion structure used for charge to voltage conversion in a solid state image sensor having an output amplifier provided with a gate electrode, comprising the steps of: (a) growing a gate oxide on a substrate of a given conductivity type; (b) forming the gate electrode for the output amplifier on the gate oxide and patterning the gate electrode so as to create an opening through it; (c) introducing through the opening a dopant of a conductivity type opposite to the given conductivity type so as to create a floating diffusion region in the substrate; and (d) creating an ohmic contact between the floating diffusion region and the gate electrode.
