摘要： A charge splitter for separating an incoming charge packet into two outgoing packets while the charge is in a static state, i.e., not while it is flowing down a channel or over a barrier. A splitting gate may have a biasing charge impressed upon it, such as via the application of voltage or current sources to opposite ends thereof, applying a bias to a semiconductor body portion of the gate structure, or by physically separate the splitting gate into multiple sections that each have different applied voltages or currents When discharge barrier gates are operated, different amounts of charge will thus flow to different output storage gates.

摘要： A back illuminated, buried channel, multiphase charge-coupled device for imaging has a photosensitive volume bounded by silicon dioxide layers on both the front and back. The dark noise generated by these interfaces with the photosensitive volume is reduced by negative bias potential pinning the front at about -6V and the back at about -0.4V. To create fixed barrier phases at the front for accumulation within each pixel comprised of multiphase gates, positive ions are implanted at one phase gate while the others are phase clocked into channel inversion. Otherwise the phase clock of at least one gate must be controlled to provide accumulation to provide a "partial-inversion" technique. The negative bias at the back may be varied to adjust the quantum efficiency of the device, thus providing electronic shuttering.

摘要： A multidirectional charge transfer device configured in a charge storage medium. The device includes an array of charge storage regions. Each of said charge storage regions includes a plurality of first gates, each of which is arranged in a first portion of each charge storage region, a plurality of second gates, each of which is arranged in a second portion of each charge storage region, a plurality of third gates, each of which is arranged in a third portion of each charge storage region, and a plurality of fourth gates, each of which is arranged in a fourth portion of each charge storage region. The plurality of gates and charge storage regions are configured to define at least three bidirectional charge transfer paths which are noncollinear with respect to each other. The plurality of gates are sequentially biased to establish charge transfer along one of said bidirectional charge transfer paths and forming blocking potentials to charge transfer in the remaining charge transfer paths.

摘要： A charge transfer device having one or more control electrodes connected to switching means so that the electrode can perform two functions. Normally the electrode is used for charge transfer but it may be switched to act as a blocking electrode for blocking the charge present underneath it for one or more clock phases. This permits the device to be formed as a filter, an analog-to-digital converter or digital-to-analog converter in a simple and inexpensive manner. The charge transfer channel may be split into sections using isolation diffusions.

摘要： A charge-coupled device comprises a p type silicon substrate (130), a plurality of n type impurity regions (121) of a high impurity concentration, a plurality of n type impurity regions (140) of a low impurity concentration, a silicon oxide film (150) for defining a channel region (10), a gate oxide film (110), a plurality of gate electrodes (21, 31, 41, 51, 22, 32, 42 and 52) and clock bus lines (70, 80, 90 and 100) for applying a clock signal to the respective gate electrodes. The n type impurity regions (121) and (140) are formed alternately in the channel region (10) along a direction perpendicular to the charge transfer direction, whereby the potential in the channel region (10) changes in the above described perpendicular direction. The change of the potential causes a strong electric field in the channel region (10) in the above described perpendicular direction, which serves to prevent carriers from freezing to an impurity level at a low temperature. Thus, the transfer efficiency of carriers is improved.
