摘要:
A CCD arrangement which includes a semiconductor layer of a first conductivity type, a layer of insulating material on the semiconductor layer, a row of shift electrodes on the insulating layer. The row of shift electrodes on the insulating layer are fed with pulse train voltages displaced in phase relative to one another. The charges are fed to an output end diffusion zone of the opposite conductivity type which has previously been brought to a reference potential and then released from the latter producing a state which is not bound in potential to the exterior. One of the shift electrodes is connected via a terminal to a transistor switch which intermittently supplies the assigned pulse train voltage, and to the gate of a field effect capacitor whose counter electrode is fed with a periodic pulse voltage. The rising flanks of this pulse voltage are each delayed relative to the times at which the assigned pulse train voltage is interrupted. The terminal of the aforesaid one shift electrode is connected to the gate of a field effect capacitor which serves as a signal output.

摘要:
A monolithic integrated circuit arrangement is disclosed which is formed of a group of one-transistor storage elements arranged on a semiconductor layer. Each storage element has a selection field effect transistor and a storage capacitor. The storage elements are arranged in pairs. First and second storage capacitors of each pair are combined to save storage area. In one embodiment, a first conductive coating overlying a surface of the semiconductor layer is employed as a common second electrode for all the storage capacitors. Additional second conductive coatings insulated from the first conductive coating and arranged thereover form the first electrodes for the storage capacitors. In another embodiment a first conductive coating is employed as a common second electrode for the storage capacitors. A second conductive coating is utilized as a first electrode for some of the storage electrodes while an inversion or diffusion layer is utilized as a first electrode for the other storage capacitors. In a final embodiment a first conductive coating over the semiconductor layer is utilized as a common second electrode for all of the storage capacitors. A second conductive coating over the first conductive coating and insulated therefrom is utilized as a first electrode for some of the storage capacitors whereas other storage capacitors have their first electrode formed as an inversion layer adjacent to a shift electrode.
摘要:
A process for producing an integrated circuit having a pair of complementary field effect transistors, one being a J-FET and the other being a MIS-FET. The process includes a series of masking and ion implantation steps carried out in part for both transistors at the same time. The doping of the region between the source and drain is increased for the MIS-FET at the same time that the doping of the channel of the J-FET is increased in order to control the threshold voltage of the MIS-FET.
摘要:
A dynamic storage element has an electrically insulating layer carried on a substrate of semiconductor material. A conductor path, provided with a terminal, is arranged on the electrically insulating layer, and first and second zones, doped oppositely to the substrate, are provided on the surface of the substrate. The zones are spaced from one another. In that region of the substrate between the zones the substrate is more highly doped with dopants of the same type as those contained in the substrate and the conductor path extends above the highly doped region.
