Abstract

PURPOSE:To make it possible to protect an corrosion part from process gas by a method wherein in case a material to be treated is treated with gas in a reaction container, the treatment is performed in a state that noncorrosive gas is sprayed on the corrosion part, which is caused by the gas, in the container. CONSTITUTION:A turntable 14 mounted with a wafer boat 17, in which semiconductor wafers 16 are housed, is inserted in an inner cylinder 3 of a reaction container 1 in a preheating state along with a cap part 9 and the container 1 is sealed with the cap part 9. After this, while the interior of the container 1 is held at a prescribed degree of vacuum, raw gas is fed in the container 1 from a process gas introducing tube 24 to perform a treatment for the wafers 16. At this time, noncorrosive gas is circulated in a magnetic fluid seal unit 12, that is, purge gas is circulated in a primary side purge gas flow path 18 and this purge gas is fed in a purge gas feeding space 23 from a secondary side purge gas flow path 19 through a pair of flanges 20 and 21. This fed purge gas makes higher the pressure in the vicinity of the unit 12 than that in the container 1 and prevents corrosive process gas from reaching the unit 12.
