Abstract
The invention relates to an image sensor for use in the facsimile device, image reader, digital scanner and the like. In this image sensor, the photodiodes and blocking diodes formed on an insulating board are insulated by a transparent interlayer insulating film and are connected in series and opposite polarity by coupling electrodes through contact holes in the transparent interlayer insulating film. This image sensor features a high reading speed and a low dark output noise.
