CHARGE COUPLED DEVICE

摘要

PURPOSE: A charge coupled device is provided to enhance transfer efficiency by differently forming a structure of a V-H interface portion. CONSTITUTION: A plurality of photo diode regions(31) is regularly arranged. A vertical charge transfer region(32) is composed between the photo diode regions(31) for transferring a photoelectric converted charge in a vertical direction. A horizontal charge transfer region(36) is composed for transferring the vertically transferred charged in a horizontal direction to be sensed in a floating diffusion region. First and second poly gate(34,35) are repeatedly composed on the vertical charge transfer region(32) for being electrically divided each other and being overlapped.
