Abstract:
1. A solid-state imaging device of the amplification type, comprising, a plurality of picture elements arranged two-dimensionally, each picture element comprising: a semiconductor light-receiving region of a first conductivity type serving as a photoelectric conversion element, the photoelectric conversion element being disposed in a common well of a second conductivity type formed in a semiconductor substrate of the first conductivity type; a semiconductor region of the first conductivity type serving as a source or drain of a transistor for amplification, the semiconductor region being disposed in the common well; contacts for supplying a reference voltage to the common well, the reference voltage contacts being disposed outside the outermost picture elements and in each picture element; a wiring connected to the reference voltage contacts for supplying a reference voltage; and a power source contact for supplying, to the semiconductor region of the first conductivity type, a power source voltage for driving the transistor for amplification, the power source contact being disposed in each picture element, wherein the power source contact is connected by a wiring to a power source, the power source wiring being separate from the reference voltage wiring, wherein one of either the reference voltage contacts or the power source contacts is connected to a wiring arranged at every row or every column of the picture elements and the other of the reference voltage contacts or the power source contacts is connected to a shielding layer having a light-receiving window formed above the wiring arranged at every row or every column of the picture elements, and wherein the wiring arranged at every row or every column of the picture elements is connected to the reference voltage contacts and is disposed between two control lines for controlling a semiconductor element inside the picture element.
