    摘要: An object of the present invention is to provide a method of forming a thin film of excellent quality by generating discharge plasma using gaseous raw material including a carbon source under an atmosphere of a relatively high pressure of 100 Torr or higher. A substrate 6 is mounted on at least one of opposing electrodes 4 and 5. A pulse voltage is applied on the opposing electrodes 4 and 5 under a pressure of 100 to 1600 Torr in an atmosphere containing gaseous raw material “A” including a carbon source to generate discharge plasma. A thin film 7 is thus formed on the substrate 6. The pulse voltage has a pulse duration of 10 to 1000 nsec.

    摘要: A substrate 6 is provided over at least one of opposing electrodes 4 and 5. A pulse voltage is applied on the opposing electrodes 4 and 5 in an atmosphere containing gaseous raw material including a carbon source to generate discharge plasma so that a thin film 7 is formed on the substrate 6. The applied pulse voltage includes positive pulse and negative pulses. The positive pulse has a pulse half value width of 1000 nsec or shorter and said negative pulse has a pulse half value width of 1000 nsec or shorter.

    摘要: A sapphire single crystal wafer 11 having a diameter not less than two inches and having an off-angled surface which is obtained by rotating an R (1-102) surface about a [11-20] axis by a given off-angle is introduced in a CVD apparatus, and a double-layer structure of first and second aluminum single crystal layers 12 and 13 is deposited on the off-angled surface of the sapphire single crystal wafer by MOCVD. The thus deposited aluminum single crystal layer 13 has (1-210) surface. The first aluminum nitride single crystal layer 12 serves as a buffer layer and has a thickness of 5-50 nm, and the second aluminum nitride single crystal layer 13 has a thickness not less than 1 &mgr;m. The off-angle is preferably set to a value not less than ±1°, much preferably a value ±2°, more preferably a value not less than −3°, and particularly preferable to a value within a range from −2°-+10°. The thus obtained aluminum nitride single crystal layer 12, 13 has no clack formed therein, has an excellent piezo-electric property, and has a high propagating velocity for surface acoustic wave.

    摘要: A sapphire single crystal wafer 11 having a diameter not less than two inches and having an off-angled surface which is obtained by rotating an R (1-102) surface about an axis in a negative direction by a given off-angle not less than 2° is introduced in a CVD apparatus. While the sapphire substrate is kept at a temperature of about 950° C., a buffer layer made of gallium nitride or aluminum-gallium nitride is first deposited with an average thickness of 0.1-0.2 &mgr;m, and then an aluminum nitride single crystal layer is deposited with an average thickness not less than 2 &mgr;m. The thus obtained aluminum nitride single crystal layer does not have a significant amount of cracks, has an excellent piezoelectric property, and has a high propagating velocity.
