SAUCER FOR ESCAPED MELT IN APPARATUS FOR PULLING UP SINGLE CRYSTAL

摘要

The present invention provides a catch pan for melt leakage provided under a crucible at a bottom portion of a chamber in a single crystal pulling apparatus based on the CZ method, wherein the catch pan for melt leakage comprises at least a bottom portion and a barrel portion, and the bottom portion and the barrel portion are connected by screw-fitting or by using a tap bolt. There is provided a catch pan for melt leakage provided in a single crystal pulling apparatus, which can, even if a melt flows out of the crucible by a certain possible cause in a CZ method single crystal pulling apparatus, prevent the melt flowed out from reaching lower mechanisms including metal parts, piping and so forth, and thereby prevent bad influences on operators and peripheral equipments.
