  • Method for the epitaxial deposition of a semiconductor material by electrical polarization of a liquid phase at constant temperature
    Patent number: 4133705
    Abstract: A method for the epitaxial deposition of a semiconductor by electrical polarization of a liquid phase at constant temperature.Outside the growth time the polarization is applied in the direction of the cooling by the Peltier effect with a current density which is lower than the threshold which causes the growth and which lies near same.
    Type: Grant
    Filed: July 1, 1977
    Date of Patent: January 9, 1979
    Assignee: U.S. Philips Corporation
    Inventor: Elie Andre
  • Epitaxial growth apparatus
    Patent number: 3990392
    Abstract: Method of and device for the epitaxial deposition of a layer of a semiconductor material on a substantially flat side of a crystalline substrate from a melt which contains the semiconductor material in which a crucuble is used having a slide and the contact between the melt and the substrate is effected by moving said slide. The slide may form a separation between a space in which the melt is formed and a space in which the substrate is situated. The slide may also comprise a recess for the substrate.
    Type: Grant

  • Liquid phase epitaxy
    Patent number: 3933123
    Abstract: A method of and a device for the epitaxial deposition of a layer on a monocrystalline substrate from a material in the liquid state, in which during the deposition process apportioned quantities of a second material are added to the said material in the liquid state, a jig being used having a plurality of vertically spaced, fixed and slidable walls for controlling the addition. Application inter alia for the provision of semiconductor layers, for example, of material of the type A.sup.III B.sup.V, in particular from mixed crystals.
