  • Novel integrated circuit and method of manufacturing same
    Patent number: 4069493
    Abstract: An integrated circuit comprises a high-resistivity substrate 1 which virtually insulates the various integrated components of the circuit from one another and reduces the parasitic capacitances. This components are constituted by ion implantation through high-precision masks, without exceeding 800.degree. C in temperature. This is the case with the source 3, the gate 9 and the drain 4, of the field-effect transistor (shown in FIG. 1).
    Type: Grant
    Filed: April 26, 1976
    Date of Patent: January 17, 1978
    Assignee: Thomson-CSF
    Inventor: Albert Bobenrieth
  • Logic circuits-employing junction-type field-effect transistors
    Patent number: 3969632
    Abstract: A logic circuit uses a junction-type field-effect transistor.The element comprises a transistor whose gate, by means of Zener diodes or forward-biased diodes is placed at a fixed potential so that it is blocked when one of its inputs carries the 0 level, and at another fixed potential, such that it is conductive, when all the inputs carry the 1 level.
