Abstract
A high-quality crystal sheet is provided. An apparatus for use in producing a crystal sheet includes a substrate having a main surface on which a crystal sheet is formed, a crucible holding a melt therein, a movable member holding the substrate to move it to bring its main surface into contact with the melt and then move the substrate away from the melt, and cooling means for cooling the movable member.
Claims10
A method of producing a crystal sheet, the method comprising:
- bringing a main surface of a cooled plate into contact with a melt;
- moving away from the melt the main surface of said plate brought into contact with the melt, to solidify and grow a crystal sheet on said main surface;
- removing the crystal sheet from said plate;
- and
- wherein the step of removing the crystal sheet from the plate includes guiding the crystal sheet grown on said plate to output the crystal sheet from a heating chamber, and removing the crystal sheet from said plate and collecting the crystal sheet so that the crystal sheet is removed from the plate outside of the heating chamber.
