The required thin film is formed on the substrate 04 by activating (radicalizing) the RF power energy applied to the F electrode 02 to cause a chemical reaction on the surface of the substrate 07. The gas that has been involved in the film formation is discharged from the discharge hole 08 to the outside of the film formation chamber 01 as shown by arrow B.

The heater 05 is for heating the substrate 04 under the required film forming conditions, and is installed on the back surface of the substrate electrode 03. The reaction gas in the film forming chamber 01 is ejected from the inside of the RF electrode 02 to the substrate side, but since the volume of the space around the RF electrode 02 and the substrate electrode 03 is larger than the facing space, the volume is larger. , As shown by arrow C, there is a tendency to flow in the direction of the gas discharge hole before reaching the substrate 04. Further, the electric field E formed between the RF electrode 02 and the substrate electrode 03 spreads in the space around the above, and the equipotential surface on the substrate surface is not uniform. Therefore, the thickness of the thin film formed on the substrate 04 becomes thin at the block portion around the substrate, and a uniform film thickness cannot be formed over the entire surface of the substrate.

FIG. 5 is a schematic diagram for explaining the relationship between the reaction gas flow path and electric field in the film forming chamber and the film thickness to be formed, and the same reference numerals as those in FIG. 4 represent the same parts. As shown in the figure, the reactive gas ejected from the RF electrode 02 is indicated by arrows C 1 and C 2 from the central portion of the substrate 04 toward the gas discharge holes 08 provided at the four corners of the film forming chamber 01. As a result, the equipotential surface on the substrate surface becomes uneven.

Therefore, the region R in which the thin film formed on the substrate 04 is uniformly deposited remains in the range of about 70% from the central portion of the substrate as shown in the direction of each side of the substrate surface. It should be noted that DD x and DD y in the same figure indicate the length dimensions of the sides of the RF electrode 02. Therefore, in the past, in order to form a uniform film on the entire surface of the substrate, the RF was used to cover the 70% uniform film forming area with respect to the size of the substrate.
It was necessary to secure the dimensions of the electrodes with respect to the dimensions of the substrate.

As described above, in the conventional technique, the flow of the reaction gas in the film forming chamber is not uniform with respect to the substrate surface, and the RF electrode and the substrate electrode are not separated from each other. Since the equipotential surfaces between the substrates are not uniform, it is difficult to make the thin film formed on the substrate uniform over the entire surface of the substrate, and the dimensional relationship between the RF electrode and the substrate is set to an optimum value. No consideration is given to what to do.
