METHOD AND EQUIPMENT FOR PRODUCING BLOCKS OF A SEMICONDUCTING MATERIAL

摘要

The invention relates to an equipment (10) for producing blocks of a semiconducting material, comprising at least one housing (12) containing a neutral gas atmosphere, said housing including a fusion system (27, 32, 40) adapted for melting the semiconducting material in a crucible (24); a purification system (50) for removing the impurity of the molten semiconducting material in the crucible; a thermal transfer system (32) for cooling the base of the crucible and a heating system (40) for heating the free surface (63) of the molten semi-conducting material purified in the crucible in order to enhance the solidification of the semiconducting material; and a displacement system (18) for displacing the crucible (24) containing the molten and purified semiconducting material up to a heating system and/or a system for displacing the heating system up to the crucible containing the molten and purified semiconducting material.
