  • Single crystal-growing method and apparatus
    Patent number: 6036775
    Abstract: A process is disclosed for continuously producing a single crystal by drawing downwardly a melt of a single crystal raw material, wherein a single crystal body grown from the melt is continuously pulled downwardly, and a plurality of single crystal products are continuously formed by intermittently cutting the single crystal body being downwardly moved.
    Type: Grant
    Filed: July 21, 1999

  • Process and apparatus for the production of films of oxide type single crystal
    Patent number: 5603762
    Abstract: A process is disclosed for producing a film of an oxide type single crystal on a substrate of such an oxide type single crystal by epitaxially growing the oxide type single crystal on the substrate through contacting the substrate onto a melt in an overcooled state. The substrate of the oxide type single crystal is contacted with the melt held in a first furnace, and the substrate of the oxide type single crystal is held inside a second furnace separated from said first furnace, and the temperature of the substrate is adjusted in the second furnace. An oxide type single crystal film-producing apparatus is also disclosed.
