Apparatus and process for the continuous fabrication of a polycrystalline silicon ingot

摘要

An installation for the continuous fabrication of a bar of multicrystalline silicon in an essentially cylindrical crucible, heated in its upper part by induction so that the upper part of the silicon may be melted and being associated with means for silicon re-feeding, has means (30 - 37) for periodically aspiring a part of the molten silicon.
