Charge-coupled device - has parallel section with first charge storage electrode shaped to be wider than succeeding electrodes at least over each channel

摘要

The device comprises a series register having charge storage electrodes for defining charge storage wells and charge transfer electrodes for transporting charge between the charge storage wells. A parallel section has channels extending transversely of the series register, the parallel section having charge storage electrodes spaced apart along the channels. Each charge storage electrode extends transversely over the channels to define a respective charge storage well with each channel to provide a respective row of charge storage wells extending trans -versely of the channels and having charge transfer electrodes for transferring charge between adjacent rows of charge storage wells. A transfer gate transfers charge between the series register and an adjacent row of charge storage wells defined by the channels and a first charge storage electrode of the parallel section. The first charge storage electrode of the parallel section is shaped so that, at least over each channel, the first charge storage electrode is wider than succeeding charge storage electrodes of the parallel section.
