Abstract
A barrel type vapor-phase growing apparatus includes a reaction cylinder with a seal plate provided for sealing the upper end of the reaction chamber. A radio-frequency heating coil is provided in the reaction cylinder. A susceptor is also provided in the reaction cylinder so as to surround the radio-frequency heating coil, and a number of semiconductor wafers supported on the surface of the susceptor are heated by the radio-frequency heating coil. A rotating device is provided on the seal plate, and a suspension member is coupled with the rotating device for suspending and rotating the susceptor within the reaction cylinder such that the upper end of the susceptor is held at a position lower than the upper end of the radio-frequency heating coil.
