  • Epitaxial solid-state semiconducting heterostructures and method for making same
    Patent number: 8389995
    Abstract: A method for producing a solid-state semiconducting structure, includes steps in which: (i) a monocrystalline substrate is provided; (ii) a monocrystalline oxide layer is formed, by epitaxial growth, on the substrate; (iii) a bonding layer is formed by steps in which: (a) the impurities are removed from the surface of the monocrystalline oxide layer; (b) a semiconducting bonding layer is deposited by slow epitaxial growth; and (iv) a monocrystalline semiconducting layer is formed, by epitaxial growth, on the bonding layer so formed. The solid-state semiconducting heterostructures so obtained are also described.
    Type: Grant
    Filed: September 17, 2008
    Date of Patent: March 5, 2013
    Assignee: Centre National de la Recherche Scientifique (C.N.R.S.)
    Inventors: Guillaume Saint-Girons, Ludovic Largeau, Gilles Patriarche, Philippe Regreny, Guy Hollinger
