Abstract
A method of assembling portions of a pulling chamber of a semiconductor crystal growing machine is provided. A tension-bearing member is initially lowered to extend within and through at least a part of a pulling chamber and through a purge tube located below the pulling chamber. The tension-bearing member is attached to a purge tube-engaging device and the tension-bearing member is then raised to carry the purge tube upon the purge tube-engaging device. The purge tube can thereby be raised into a desired position within the pulling chamber. While the purge tube is raised, a purge tube holding ring can be installed within the pulling chamber and the purge tube can thereafter be lowered into an operative position during which the purge tube is supported by the purge tube holding ring.
