  • Method for continuously pulling up crystal
    Patent number: 6663710
    Abstract: An apparatus and a method that permits a seed crystal to be directed to a precise location of a melt for growing a ribbon-shaped crystal, but after the crystal has commenced growing, the ribbon-shaped crystal is continuously pulled up so as to produce a longitudinally extending crystal using a continuous pulling device. The method for producing a ribbon-shaped crystal includes growing a ribbon-shaped crystal on a seed crystal using a linear pulling device for pulling the seed crystal and a crystal growing at the end of the seed crystal in a vertical direction, and continuing to pull the ribbon-shaped crystal by using a continuous pulling device having a continuous pulling mechanism.
