Abstract
A semiconductor crystal ingot (14) is supportively engaged by an ingot handling apparatus (22) which contacts a base (38) of the ingot (14) with a base support (36) and opposite sides of a lateral surface of the ingot (14) with at least one pair of jaws (37). The jaws (37) are retained adjacent to but out of firm contact with the lateral surface of the ingot until after the support (36) firmly supports the weight of the ingot. The support and the at least one pair of jaws are retracted from a furnace (10) simultaneously in a lateral direction with no relative movement to withdraw the ingot from the furnace.
