Then, a part of the deposited reaction product 11 is peeled off, becomes dust, and falls onto the crystal substrate 2 undergoing vapor phase growth, resulting in nonuniform film thickness or change in thin film composition. I will end up. Therefore, after performing the vapor phase growth a predetermined number of times, the reaction tube 1 is divided from the lower flange 8 and removed,
It is necessary to wash the inner wall thereof, remove the deposited reaction product 11, and then connect the lower flange 8 again to degas the adsorbed gas. This degassing is performed to prevent the composition of the thin film from being changed by the incorporation of oxygen in the air into the reaction tube 1 in addition to the source gas during vapor phase growth. If the reaction tube 1 is made of metal, for example, it is heavy and difficult to handle, and there is a risk that harmful reaction products 11 deposited on the inner wall surface of the reaction tube 1 may diffuse into the atmosphere. There is a problem with sex.
