Abstract: A heat treatment jig for semiconductor silicon substrates is configured such that a cristobalitized oxide film is formed in a region where the cristobalitized oxide film is in contact with a silicon substrate backside. When said heat treatment jig is used, generation of a slip can be prevented during heat treatment. In the case where the heat treatment jig is used in combination with a shielding plate, particles are further prevented from adhering to the silicon substrate surface to maintain quality characteristics of the semiconductor silicon substrate at a higher level, and device production yield can largely be improved. The heat treatment jig can easily be manufactured by introducing a cristobalitization promoting agent to a surface or in the vicinity of a surface of the heat treatment jig, performing the heat treatment at temperatures in the range of 1000 to 1380° C., and repeating the introduction of the cristobalitization promoting agent and the heat treatment.

Abstract: A piercing mill includes a plurality of inclined rolls, a plug, a pusher, and an undriven guide roll. The pusher pushes a round billet from the rear end at least until the round billet advances for a prescribed distance after contacting the inclined rolls. The guide roll is between the inclined rolls and the pusher and includes a roll shaft and a roll surface, with the roll shaft arranged obliquely with respect to a pass line PL. The sectional shape of the roll surface is a concave arch shape. The round billet is rotated by the guide roll and the friction force generated when the round billet contacts the inclined rolls is reduced. Consequently, the wear of the inclined rolls can be restrained if the round billet is pierced and rolled while it is pushed in between the inclined rolls using the pusher.
