Abstract
Provided are an apparatus and method of extracting a silicon ingot. The apparatus for extracting a silicon ingot includes a chamber in which a silicon source material introduced into a cold crucible is melted, a primary extraction apparatus vertically movably installed in the chamber and configured to solidify the molten silicon to extract the silicon ingot, a movable apparatus configured to horizontally move the primary extraction apparatus, and a secondary extraction apparatus vertically movably installed under the chamber and configured to extract the silicon ingot in a state in which the primary extraction apparatus is moved to one side. Therefore, as the height of the extraction apparatus is reduced, manufacturing cost of equipment can be reduced and installation space of the extraction apparatus can also be reduced.
