  • Patent number: 8679952
    Abstract: A method is provided in order to manufacture a silicon carbide epitaxial wafer whose surface flatness is very good and has a very low density of carrot defects and triangular defects arising after epitaxial growth. The silicon carbide epitaxial wafer is manufactured by a first step of annealing a silicon carbide bulk substrate that is tilted less than 5 degrees from <0001> face, in a reducing gas atmosphere at a first temperature T1 for a treatment time t, a second step of reducing the temperature of the substrate in the reducing gas atmosphere, and a third step of performing epitaxial growth at a second temperature T2 below the annealing temperature T1 in the first step, while supplying at least a gas including silicon atoms and a gas including carbon atoms.

  • Publication number: 20090042375
    Abstract: A method of manufacturing a silicon carbide semiconductor device includes a step of ion-implanting an impurity in a surface of a silicon carbide wafer (1 and 2); a step of forming a carbon protection film (6) of a predetermined thickness over the entire surface of the silicon carbide wafer (1 and 2) having been ion-implanted with the impurity, by a chemical vapor deposition method that deposits a film by pyrolyzing a hydrocarbon gas; and a step of annealing the silicon carbide wafer (1 and 2) having been formed with the carbon protection film (6). Thereby, the carbon protection film (6) can be formed that contains extremely few contaminants, and prevents step bunching from creating on the surface of the silicon carbide wafer (1 and 2) and crystal defects created therein due to unbalanced thermal stress form increasing.

  • Publication number: 20050231093
    Abstract: A method of reducing a fluctuation in a cut-off voltage of a cathode for an electron tube in which a metal layer for protrusively deforming a cathode substrate when heated is formed on a surface of the cathode substrate, and an electron emissive material layer is formed on the front face of the cathode substrate directly or through the metal layer and a heater for heating the electron emissive material layer to emit a thermion from a front face of the electron emissive material layer is provided. When the front face of the electron emissive material layer is consumed and retreats, the protrusive deformation of the cathode substrate by the metal layer is induced by a heating operation of the heater so that the front face of the electron emissive material layer is correspondingly deformed protrusively.

  • Patent number: 6583561
    Abstract: The object of the present invention is to provide a gas discharge display device having improved luminous efficiency by effectively using ultraviolet ray, which is absorbed in a partition wall or a protective film and the like without contributing to excitation of a fluorescent material. By adding gadolinium to the materials excluding the fluorescent material among structures surrounding the discharge cell, ultraviolet ray having a wavelength of 315 nm is generated, which can excite the fluorescent material. The ultraviolet ray excites the fluorescent material to generate visible light, and then, electric-light conversion efficiency is improved.
