Abstract

PURPOSE: To make it possible to decompose the deposit adhered to a shroud by heating it up and it is introduced into an evacuation system having a cold trap.
CONSTITUTION: A crystal growth chamber 1 is connected to a turbo pump 14, a cold trap 16, a foreline trap 18 and a roughing vacuum pump 17 through the intermediary of a gate valve 15. The crystal growing chamber 1 is heated up to the temperature necessary for edgussing by baking by applying a current to heaters 12 and 13 in the state wherein the crystal growth chamber 1 is evacuated, and a current is applied to heaters 8W10. When a shroud 6 or 7 is heated up, the adhered matter is scattered by thermal decomposition, and lastly, it is streamed to an exhaust system together with other gas. As a turbo molecular pump is used as a evacuation pump, said matter is not stored in the pump, it is exhausted from the pump, and as the trap which in sufficiently cooled by the refrigerant such as liquid nitrogen is arranged, the deposit is readhered to the cooled surface of the trap and recovered.
