ABSTRACT:
An elongated light receiving element is formed with a plurality of parallel one dimensional light receiving arrays or lines, each of which is lead out from a substrate. Each line is tested to determine which line or lines are free of defects, and the remaining lines are disconnected from the power source. The device serves to increase the production yield of such devices, which are prone to defects when manufactured in large sizes.
