  • Process for hardening active electronic components against ionizing radiations, and hardened components of large dimensions
    Patent number: 5397735
    Abstract: The invention relates to the "hardening" (resistance to ionizing radiations) of MOS-type components. In order to avoid the effects of these radiations (creation of electron-hole pairs), there is deposited on a substrate (1) of monocrystalline Si a layer of YSZ (2), and then a thin layer of monocrystalline Si (3). The other steps of production of the components are the same as conventional.
    Type: Grant

    Date of Patent: March 14, 1995
    Assignee: Thomson-CSF
    Inventors: Louis Mercandalli, Didier Pribat, Bernard Dessertenne, Leonidas Karapiperis, Dominique Dieumegard
  • Device made of oxide superconductive material covered with ion conductive means for adjusting the doping level and T.sub.c thereof
    Patent number: 5053833
    Abstract: Disclosed is a device made of superconductive material wherein the superconducting layer is enclosed by at least one material which is a conductor of ions of one of the anionic constituent elements of the superconductive layer. This makes it possible to adjust the stoichiometry of the superconductive layer. The disclosure also concerns a method for adjusting the content of the constituent elements of the superconductive layer by electrolysis.

  • Method of reduction of a compound forming a layer on a substrate and the application of said method to the fabrication of a field-effect semiconducting structure
    Patent number: 4521951
    Abstract: The method of reduction comprises two successive steps. The first step consists in forming an electrolyte layer at the surface of the layer to be reduced which is an oxidized surface layer of a substrate. During the second step, the layer is reduced through the layer of electrolyte which is an ionic conductor for the ionizing species. The second step is carried out in a first variant by thermal reduction in a reducing atmosphere and in a second variant by exposure to a reducing plasma.
