    摘要： The present invention discloses a CVD apparatus which, together with being able to efficiently perform purging treatment after maintenance, uses for the purge gas a mixed gas of a gas having high thermal conductivity and an inert gas during heated flow purging treatment after maintenance to perform startup of the CVD apparatus while reducing the amount of time required for purging treatment. Purging treatment before semiconductor film formation is performed by repeating the pumping of a vacuum and the introduction of inert gas a plurality of times. In addition, in order to judge suitable maintenance times of semiconductor production apparatuses that perform corrosive gas treatment in a reaction chamber, the moisture concentration in reaction chamber is measured with moisture meter connected to the reaction chamber when performing the corrosive gas treatment, and maintenance times of the semiconductor production apparatus are determined according to changes in the moisture concentration when corrosive gas treatment is performed repeatedly. In addition, in order to measure the moisture of corrosive gas during processing while preventing obstruction of piping in a moisture monitoring apparatus and semiconductor production apparatus equipped therewith, a moisture monitoring apparatus, which is equipped with a pipe, of which one end is connected to reaction chamber into which corrosive gas flows, and a moisture meter connected to the other end of that pipe which measures the moisture contained in the corrosive gas introduced from the reaction chamber, is at least equipped with pipe heating mechanism that heats the pipe.

    摘要： The present invention provides a spectroscopic method for analyzing isotopes which makes it possible to simplify a system for measurement and to identify isotopes with high accuracy and sensitivity and to carry out quantitative analysis. The spectroscopic method for analyzing isotopes uses a semiconductor laser beam having as a wavelength zone a 2000 nm-wavelength band as a beam source of wavelengths of the absorption spectra of the isotopes. A reference gas is used for identification of the isotopes where the gas contains collating components having two wavelengths (W1, W2) of well-known absorption spectra in wavelength bands close to the wavelengths (w1, w2) of the absorption spectra of the isotopes.
