Very large purity silicon for semiconductors is received using the Siemens course of action; the silicon is reacted to supply trichlorosilane, that's 1st purified by distillation, then reacted with purified hydrogen on large purity silicon rods at 1150 oC to generate large purity, polycrystalline silicon with hydrochloric acid byproduct.
