Abstract:
1. A charge coupled device, comprising: a semiconductor substrate of one conductive type; a first charge coupled device having a series of electrodes linearly arranged on the semiconductor substrate and ending in a last electrode at one end remote from another end; a second charge coupled device diverged into two lines at an end of the first charge coupled device; said last electrode connecting the one end of the first charge coupled device to the second charge coupled device; detectors, each of which detects a signal transferred by one of two lines of the diverged second charge coupled device; and output devices, each of which outputs the signal detected by one of the detectors, wherein the last electrode of the first charge coupled device connecting to the diverged second charge coupled device is shaped such that the width of a transfer channel of the last electrode becomes narrower in width the further the transfer channel is from the end of the first charge coupled device in the direction of the diverged second charge coupled device.
