Abstract:
1. A solid-state image pick-up device comprising: a photoelectric conversion section; a floating diffusion section; a transfer transistor for transferring a charge generated in the photoelectric conversion section to the floating diffusion section; and a signal amplifying section connected electrically to the floating diffusion section, wherein: the signal amplifying section includes a MOS transistor, an electrical connection between the floating diffusion section and a gate electrode of the MOS transistor is formed by a same wiring layer as that including the gate of the MOS transistor, a plurality of metal layers are arranged above the same wiring layer as that including the gate of the MOS transistor, a first metal layer included in the plurality of metal layers and arranged closest to the floating diffusion section includes a light shielding metal, the light shielding metal shields the floating diffusion section from light by covering the floating diffusion section and a gate of the transfer transistor, thereover, and the floating diffusion section and the light shielding metal are not electrically shorted.
