- the SiHCl 3 gas supplied to the heating chamber 8 is heated to 700 to 1000 ° C. by the heating means 15 and decomposes as shown in the following formula (1) (heating step).
- the following reaction formula (1) is likely to occur as the heating temperature of the SiHCl 3 gas is high, in particular, becomes active when it exceeds 900 ° C..
- the SiHCl 3 gas not decomposed in the heating chamber 8, the SiCl 2 gas generated in the heating chamber 8, and the HCl gas generated in the heating chamber 8 are supplied to the mixing chamber 38 together with the carrier gas (H 2 gas).
- SiH 2 Cl 2 gas is supplied from the second storage 40 to the mixing chamber 38.

- SiHCl 3 gas is newly generated in the mixing chamber 38 by the reaction of the above formula (2).
- the temperature of the gas in the mixing chamber 38 is lower than the temperature of the gas in the heating chamber 8. Therefore, the reaction of the above formula (1) is less likely to occur in the mixing chamber 38 than in the heating chamber 8, and the generation of HCl gas is suppressed. Therefore, the vapor phase growth chamber 36 is supplied with a mixed gas having a high concentration of SiCl 2 gas and a low concentration of HCl gas.

- the rate of crystal growth of the silicon film decreases.
- the higher the concentration of HCl gas in the vapor phase growth chamber 36 the easier the reaction of the following formula (5) occurs on the surface of the substrate 32, and the rate of crystal growth of the silicon film. Becomes slower.
- the SiHCl 3 gas is decomposed into SiCl 2 gas and HCl gas in the heating chamber 8 as shown in the equation (1). Thereafter, as shown in Formula (2), HCl gas can be removed in the mixing chamber 38. For this reason, the reaction of the formula (5) hardly occurs and the growth rate of the silicon film can be increased. In the mixing chamber 38, SiHCl 3 gas is newly generated by the reaction of the formula (2). However, since the temperature of the mixing chamber 38 is lower than the temperature of the heating chamber 8, decomposition of the SiHCl 3 gas is suppressed, and generation of HCl gas is suppressed.

In the cooling chamber 38a, the gas supplied from the heating chamber 8 and the SiH 2 Cl 2 gas supplied from the second storage 40 are cooled while being mixed. Therefore, the cooling chamber 38a and the mixing chamber 38b can be regarded as the mixing chamber 38 together.
- the gas in the mixing chamber 38 can be cooled by the cooling means 64. Even if the temperature of the gas supplied from the heating chamber 8 is high, the temperature of the gas in the mixing chamber 38 can be adjusted to a desired temperature.
- the cooling chamber 38a for example, the mixed gas of the gas supplied from the heating chamber 8 and the SiH 2 Cl 2 gas supplied from the second storage 40 is cooled to 500 to 800 ° C.

- SiH 2 Cl 2 gas for example, monosilane gas (SiH 4 ), disilane gas (Si 2 H 6 ), monochlorosilane gas (SiH 3 Cl), or the like can be used.
- the temperature of the gas in the mixing chamber 38 is preferably lower than the temperature of the gas in the heating chamber 8.
- the SiH 2 Cl 2 gas not only removes the HCl gas but also generates SiCl 2 gas by decomposition. Therefore, it is particularly preferable to use SiH 2 Cl 2 gas as the silane-based gas that reacts with HCl gas.
- an impurity dopant gas may be supplied to the heating chamber 8 or the mixing chamber 38. If an impurity dopant gas is supplied, an n-type or p-type silicon film can be crystal-grown.

If silicon is used as the material of the substrate 32, since the material is the same, defects such as deformation hardly occur in the grown silicon film. If a material other than silicon is used as the material of the substrate 32, even if the temperature for heating the substrate is set close to the melting point of silicon, the substrate is unlikely to be deformed. Therefore, a high quality silicon film can be crystal-grown. As materials other than silicon, aluminum nitride and silicon carbide are particularly preferable. Aluminum nitride and silicon carbide have a thermal expansion coefficient close to that of silicon. Therefore, a higher quality silicon film can be crystal-grown.
