Abstract
In a method for growing ribbon-like crystal of crystalline substance, a seed crystal is contacted on the upper surface of melt of crystalline substance raised up to the level beyond the upper edge of a crucible, thereafter the contact interface between said seed crystal or a successively growing crystal and the melt (the solid-liquid interface) is cooled under freezing point of said crystalline substance, thereby the crystal is made to successively grow on said solid-liquid interface, while said seed crystal or said successively growing crystal is drawn out substantially in horizontal direction, wherein the circulating convection is made to cause in such a manner that high temperature melt flows underside of said solid-liquid interface, thereby the crystal growth in the direction of depth of the melt is prevented.
