摘要： The present invention includes a method for casting a silicon ingot by using a continuous casting method by means of an electromagnetic induction, and a method for cutting the silicon ingot as a starting material into plural silicon blocks. When the silicon blocks with a square section are cut out, the sectional shape of the silicon ingot is set to be rectangular. Not less than 6 pieces of equal-sized silicon blocks are cut out from the silicon ingot, thereby enabling to enhance the manufacturing efficiency to a great extent. And since the amount of excision of the edge per silicon block is reduced, the production yield can be enhanced. Further, since the proportion of columnar crystals with large grain size inside the ingot can be increased, it becomes possible to enhance the conversion efficiency of a solar battery using the silicon block as a substrate material.
摘要翻译： 本发明包括通过使用电磁感应的连续铸造法铸造硅锭的方法，以及将硅锭作为原料切割成多个硅块的方法。 当切出具有正方形截面的硅块时，将硅锭的截面形状设置为矩形。 从硅锭切出不少于6个等尺寸的硅块，从而能够在很大程度上提高制造效率。 并且，由于每块硅块的边缘切除量减少，所以能够提高生产率。 此外，由于能够提高锭内的晶粒大的柱状晶体的比例，所以可以提高使用硅块作为基板材料的太阳能电池的转换效率。

摘要： Disclosed is an electromagnetic casting method of polycrystalline silicon which is characterized in that polycrystalline silicon is continuously cast by charging silicon raw materials into a bottomless cold mold, melting the silicon raw materials using electromagnetic induction heating, and pulling down the molten silicon to solidify it, wherein the depth of solid-liquid interface before the start of the final solidification process is decreased by reducing a pull down rate of ingot in a final phase of steady-state casting. By adopting the method, the region of precipitation of foreign substances in the finally solidified portion of ingot can be reduced and cracking generation can be prevented upon production of a polycrystalline silicon as a substrate material for a solar cell.
