Abstract
A solid-state imaging device in which the possibility of defect formation in a photoconductive layer is substantially eliminated by the use of a multi-layered structure. A photoconductive film unit and a transparent electrode are formed in that order on a semiconductor substrate in which is formed a scanning circuit composed of a plurality of picture elements defined by respective electrodes on the semiconductor substrate and the transparent electrode. The photoconductive film unit is composed of a polycrystalline silicon film and an amorphous silicon film that are disposed in that order on the semiconductor substrate.
