Patent ID: 7214976

Claim:
A solid-state imaging apparatus, comprising: a plurality of photosensitive cells disposed in a matrix in a photosensitive region on a semiconductor substrate; and a driving unit for driving the plurality of photosensitive cells, wherein each of the photosensitive cells includes: a photodiode formed to be exposed on a surface of the semiconductor substrate, for accumulating signal charge obtained by subjecting incident light to photoelectric exchange; a transfer transistor formed on the semiconductor substrate, for transferring the signal charge accumulated in the photodiode; a floating diffusion layer formed on the semiconductor substrate, for temporarily accumulating the signal charge transferred by the transfer transistor, the floating diffusion layer including a contact portion that is connected to a gate electrode of an amplifier transistor; and the amplifier transistor being formed on the semiconductor substrate, for amplifying the signal charge temporarily accumulated in the floating diffusion layer, wherein a source/drain diffusion layer provided in the amplifier transistor is covered with a salicide layer, the floating diffusion layer is formed to be exposed on the surface of the semiconductor substrate in a region other than a periphery of the contact portion of the floating diffusion layer, while a region within the periphery of the contact portion is covered with a second salicide layer, and an impurity concentration of the floating diffusion layer is lower than an impurity concentration of the source/drain diffusion layer of the amplifier transistor.
