SINGLE CRYSTAL PRODUCTION APPARATUS, CRUCIBLE FOR USE THEREIN, AND METHOD OF PRODUCING SINGLE CRYSTAL |
摘要 |
The production apparatus is used in production of single crystals by solution growth techniques. The production apparatus includes a seed shaft, a crucible, and a drive source. The seed shaft has a lower end surface to which a seed crystal is to be attached. The crucible contains a solution from which a single crystal is made. The drive source causes the crucible to rotate, and also varies the rotational speed of the crucible. The inner peripheral surface of the crucible includes a flow control surface which defines a non-circular cross-sectional shape. This single crystal production apparatus is capable of strongly stirring the solution contained in the crucible. |
