Abstract

PURPOSE: To improve the quality of a ribbon-like crystal in growing the ribbon- like crystal through a die dipped in a melt, by means of melt introductory grooves at the center and both ends of the bottom of the die for supplying the melt without uneven temperature to the top of the die.
CONSTITUTION: A semiconductor melt 22 in a crucible 1 is lifted through grooves 12 and 13 at the center and grooves 15 and 16 at both ends of the bottom of dies 3, 4 and 11 dipped in a melt 2 toward the top of the die 11. The melt 2 in the grooves 12, 13, 15 and 16 is joined at a groove 14 at the top of the die 11 and pulled up with the uniform temperature to form a ribbon-like crystal. Thus, the quality of the ribbon-like crystal 5 is improved.
