  • Publication number: 20230265580
    Abstract: In a vapor phase growth system in which a preheating ring is provided around a susceptor, the flow rate of source gas can be adjusted by changing the position of the susceptor, and the effect on the film thickness variation of a semiconductor single-crystal layer due to the changes of the position of the susceptor is caused to be less likely to occur. The susceptor is raised/lowered by a susceptor position changing mechanism, and the height position of holding the susceptor in a reaction vessel body can be changed. A preheating ring position changing mechanism changes the height position of holding the preheating ring in the reaction vessel body based on raising/lowering of the preheating ring in accordance with the changes of the height position of holding the susceptor.
