Charge coupled device having diverged channel

Abstract

A charge coupled device comprises a semiconductor substrate of one conductive type, a first charge couple device having a series of electrodes linearly arranged on the semiconductor substrate, a second charge coupled device diverged into tow lines at an end of the first 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 a plane shape of a last electrode of the first charge coupled device connecting to the diverged second charge coupled device is a shape wherein a length of a transfer channel of the last electrode becomes shorter as going far from a right angled direction of a transfer direction of the first charge coupled device starting from a boundary part of divergence of the diverged second charge coupled device.
