Abstract:
1. A method of manufacturing a semiconductor device comprising: connecting at least part of a path extending from a processing chamber to a detoxification device through a vacuum pump by a flexible tube having a tube body made of hard material, the tube body having projected parts and depressed parts and a cover provided over an outer surface of the tube body, the cover being made of elastic material, the cover being in contact with around the projected parts of the tube body and formed over the depressed parts of the tube body so that a vacant space is formed between the tube body and the cover; wherein the cover is made of a material selected from the group consisting of heat shrinkable silicone rubber and electron beam bridging soft flame resistance polyolefin resin: introducing a purge gas into the processing chamber; disposing a semiconductor substrate within the processing chamber; activating the vacuum pump to bring the processing chamber into a pressure-reduced state; and effecting a process on the semiconductor substrate under the pressure-reduced state.
