Abstract

A vapor phase growth system includes a process chamber that includes a susceptor lifting mechanism that raises and lowers the susceptor between a first position and a second position. With the susceptor in the first position, the top surface of the susceptor is above the bottom surface of the preheating ring, and a source gas distribution space with a predetermined height dimension is secured between the top surface of the susceptor and the bottom surface of a ceiling plate of the reaction vessel body. With the susceptor in the second position, the top surface of the susceptor is located below the bottom surface of a preheating ring, and a substrate loading/unloading space, which has a greater height dimension than that of the source gas distribution space, is secured between the top surface of the susceptor and the bottom surface of the preheating ring.
