SILICON REFINING EQUIPMENT AND METHOD FOR REFINING SILICON |
摘要 |
<p>In this method for refining silicon by vacuum melting, the falling of impurity condensate from an impurity trap located above a crucible and contamination of the molten silicon are prevented. A crucible (4) for housing molten silicon (3), and a heating means (5) for heating the crucible (4) are located inside a treatment chamber (2) equipped with a vacuum pump (1); further provided are: an impurity trap having an impurity condensation unit for cooling and condensing the vapor of impurities evaporating from the liquid surface of the molten silicon; and a contamination prevention device for preventing contamination of the molten silicon, having an impurity catch unit for catching impurities when impurities trapped by the impurity trap fall.</p> |
