Abstract:
A method for handling portions of a pulling chamber of a semiconductor crystal-growing machine, comprising:(a) attaching a purge tube ring removal tool to a tension-bearing member, wherein the ring removal tool includes a bottom surface and a ring support member spaced from the bottom surface;(b) pulling said tension-bearing member up within said pulling chamber and thereby raising said ring removal tool into engagement with a purge tube ring such that the ring support member engages the purge tube ring;(c) releasing said purge tube ring from said pulling chamber while the ring removal tool is engaged with the purge tube ring;(d) thereafter lowering said tension-bearing member and thereby lowering said ring removal tool beneath said pulling chamber with said purge tube ring carried thereon; and(e) placing the bottom surface of the ring removal tool upon a surface while continuing to support the purge tube ring upon the ring support member in a spaced relationship from the surface.
