Abstract: PURPOSE:To enable the automatic locking of a tray to a revolving shaft and to prevent the disengagement of the tray, the jumping of a wafer and the vibration of the tray by providing the part where the revolving shaft and the tray placed thereon are superposed with a pneumatically operated locking mechanism. CONSTITUTION:The tray 1 which is placed horizontally on the top end of the revolving shaft 5 disposed perpendicularly in a reactor is rotationally driven by the revolving shaft and the gaseous raw material in the reactor comes into contact with the wafer 3 placed atop the tray 1 and rotated by the tray, by which the thin film is grown in a gaseous phase on the surface of the wafer 3. The part where the revolving shaft 5 and the tray 1 are superposed of this device is provided with the pneumatically operated locking mechanism 14 for locking the tray 1 to the revolving shaft 5. After the preparation is finished, gas is supplied from a passage 23a into the large-diameter hole part 15b of a large-diameter piston 16b and a moving body 16 is lowered. As a result, a locking ball 19 is lowered from a recessed part 22 for releasing the pressing of the ball and is pressed toward a fitting shaft 20. The revolving shaft 5 and the fitting shaft 20 of the tray 1 are thus automatically locked by the locking ball 19.
