Abstract:
An image sensor includes a unit cell having a plurality of pixels; the unit cell comprising an amplifier input transistor that is shared by the plurality of pixels; a plurality of floating diffusions that are joined by a floating diffusion interconnect layer and are connected to the amplifier input transistor; and an interconnect layer which forms an output signal wire which shields the floating diffusion interconnect layer.
