| 20100143231 | Method and Apparatus for Manufacturing Silicon Ingot - Provided are a novel method and novel apparatus for manufacturing a silicon ingot that make it possible to reduce manufacturing steps and also reduce required electric power. A method for manufacturing a silicon ingot, including the step of heating and melting, in a crucible, an element which can undergo eutectic reaction with silicon and has a lower eutectic point than the melting point of silicon when made into silicon alloy, and a metallic silicon, thereby generating an alloy melt, and the step of using the eutectic reaction for the alloy melt to subject the silicon to low-temperature solidification refinement, and further producing the silicon ingot from the alloy melt by a pulling method is provided. | 06-10-2010 |
