The reaction gas introduced from the reaction gas inlet 8 is
After passing through the gas holes of the current plate 5, the wafer 3 is supplied from the upper ceiling to the main surface of the wafer 3 immediately below, substantially vertically. But,
Since the rotating body 4 rotates, the gas above the rotating body 4 is discharged to the outer peripheral side of the rotating body 4. As a result, the gas collides with the side wall of the cylindrical body 1 and forms a vortex A on the side wall of the cylindrical body, as schematically shown in FIG. By the way, usually, the rotating body 4 is heated, and the discharged gas is also heated by the rotating body 4, so that when it comes into contact with the side wall, a solid deposit is formed there. Then, the deposits are separated by the vortex of the gas and carried to the main surface of the wafer 3, and the wafer 3 may be contaminated.

As a conventional example, a method for preventing contamination of a normal pressure CVD apparatus is known (Japanese Patent Laid-Open No. 4-34156).
9). In this method, in a normal pressure CVD apparatus, nitrogen gas is injected from a supply pipe and injected vertically downward from an injection port.
A curtain of nitrogen gas is formed along the inner wall surface of the intermediate ring and the housing, and the nitrogen gas is discharged from a plurality of exhaust ports to form a Si gas.
This is to prevent O 2 fine particles from being deposited on the inner wall surface. However, this type is essentially different from the technique of forming a uniform film by uniformly flowing a reaction gas onto the main surface of a wafer using a current plate as in the present invention.
