    摘要: A method for manufacturing a semiconductor device in which crystal defects are generated in a semiconductor crystal by irradiating a semiconductor substrate (1) with a particle beam. In the preceding process of the irradiation process, the substrate (1) is heat-treated such that the temperature of the substrate (1) is raised rapidly in ten minutes to 550-850 °C and maintained for one second to 60 minutes. Crystal defects are generated in the crystal by irradiating the crystal with such a particle beam as an electron beam, the life time of carriers is shortened, and accordingly the switching speed is increased, not lowering the electric characteristics such as the current amplification factor. Thus a semiconductor device having both a high switching speed and good electric characteristics is fabricated.

    摘要: Die Konzentration der Innenstörstellen in einer Halbleiter­scheibe wird in einem zweistufigen Wärmeverfahren gesteu­ert. In einer Konzentrationsreduktionsphase wird die Scheibe schnell auf eine erhöhte Temperatur im Bereich von ungefähr 900 bis 1350° C erwärmt, was zu einer teilweisen oder gesamten Auflösung von ausscheidbaren Verunreinigungen in der Scheibe führt. In einer Konzentrationssteigerungs­stufe werden die Scheiben einem Temperverfahren bei relativ niedriger Temperatur, bei dem die Dichte der potentiellen Innenstörstellen erhöht wird, unterworfen.
    Durch entsprechendes Steuern der Verfahrenstemperaturen und Behandlungszeiten können die zwei Stufen in jeder Reihen­folge durchgeführt werden, um Scheiben zu erhalten, die Innenstörstellenkonzentrationen innerhalb eines gewünschten Bereichs aufweisen.

    摘要: A process for the manufacture of a gallium rich gallium nitride film is described. The process comprises (a) preparing a reaction mixture containing a gallium species and a nitrogen species, the gallium species and the nitrogen species being selected such that, when they react with each other, gallium nitride is formed; and (b) growing the gallium rich gallium nitride film from the reaction mixture, by allowing the gallium species to react with the nitrogen species and to deposit gallium nitride on a substrate selected from the group consisting of silicon, glass, sapphire, quartz and crystalline materials having a lattice constant closely matched to gallium nitride, including zinc oxide, optionally with a zinc oxide buffer layer, at a temperature of from about 480 °C to about 900 °C and in the presence of a gaseous environment in which the partial pressure of oxygen is less than 10 Torr, wherein the ratio of gallium atoms to nitrogen atoms in the gallium rich gallium nitride film is from 1.01 to 1.20. The invention also provides the option of annealing the gallium rich gallium nitride film at a temperature of from about 20 °C to about 650 °C and for a time sufficient to decrease the resistivity of the film so that it becomes electrically conductive, for instance to a resistivity below 100 ohm.cm.

    摘要: Disclosed is a method of manufacturing a semiconductor device wherein a corpuscular beam is radiated to a semiconductor substrate to create crystal defects therein, characterized in that said semiconductor substrate is subjected to a heat treatment, e.g. for 1 second to 60 minutes, wherein rapid heating-up, e.g. raising temperature to 550 to 850 °C within 10 minutes, is done in a process prior to that of carrying out of the radiation with a corpuscular beam. By doing so, there is provided a semiconductor device which is free from degradation in electrical characteristics such as current amplification factor and has an increased switching speed, even where crystal defects are created through the radiation of corpuscular beam such as an electron beam to shorten the carrier lifetime. Thus, the inventive semiconductor device is satisfied by both requirements of switching speed and electrical characteristic.
