ABSTRACT:
The amplification type solid-state imaging device of this invention includes amplification type photoelectric converting elements arranged in a matrix. Each of the amplification type photoelectric converting elements includes: a transistor formed at a surface of a semiconductor substrate, for accumulating signal charge generated from incident light on a portion of the transistor at the surface of the semiconductor substrate and outputting an output signal comprising a change in an electric signal corresponding to the accumulated signal charge; a gate region formed adjacent to the transistor, including a portion of the semiconductor substrate, an insulating film formed on the portion of the semiconductor substrate, and a gate electrode formed on the insulating film, the gate region allowing the accumulated signal charge to move from the surface of the semiconductor substrate to the inside of the semiconductor substrate; and an output impedance converting section connected to the photoelectric converting elements which sequentially receives the output signals from the amplification type photoelectric converting elements, the output impedance converting section including a driving transistor driven with the output signals and a load transistor.
