Abstract

To increase monocrystal growing speed, it is necessary to increase temperature gradient (dT/dX) within the solid-phase monocrystal at the solid- liquid interface. Since drawn-up monocrystal is always heated by the radiation heat from the heat generator, it is preferable to reduce the temperature of the heat generator. However, where the temperature of the heat generator is reduced, there exists a problem in that the surface of the melted liquid is readily solidified at the position where the liquid adjoins to the inner wall of the crucible. To overcome the above problem, the heat generator is so constructed that the upper portion of the melted liquid is heated to a higher temperature as compared with the lower portion of the melted liquid. <IMAGE>
