Abstract

PURPOSE:To allow an uniform and reproduceable polymerizable film to be obtained by providing a plasma generating tube of which surface on an inner wall being coated with macromolecular insulation composed of the same constituent as monomer gas to reduce influence of etching function. CONSTITUTION:A plasma generating tube 17 into which inactive gas and monomer gas are introduced is supplied with a high frequency power through a high frequency coil wound on the circumference of the plasma generating tube to generate discharge. This discharge generates a radical and forms a polymerizable film and, also, it generates ions. The ions have an etching function and etches an inner wall of the plasma generating tube 17. If the inner wall of the plasma generating tube 17 is formed by macromolecular insulation of the same constituent as monomer gas, the gas constituent during discharge does not change even if the inner wall of the plasma generating tube 17 is subjected to etching. Thus, a stable and uniform polymerizable film can be obtained.

Regarding the conventional thin film forming apparatus configured as described above,
The operation will be explained below. The sample 3 to be coated with a thin film is attached to a glass plate with double-sided adhesive tape or the like, and placed inside the plasma generating tube 1. The pressure in the plasma generation tube 1 is reduced to at least 0.11 olTon or less by a vacuum pump installed at the end of the vacuum outlet 5,
After that, inert gas (e.g. argon) is introduced from gas inlet 4.
and Mono 3 Pe ・Introduce margas while checking the flow rate. If the monomer gas is discharge-prone, it is not necessary to introduce an inert gas. The pressure inside the plasma generating tube 1 after introducing the monomer gas is not limited as long as the discharge is stable, but
Generally, it is about 0.1 to 2.0 tons. After the above settings, power is applied to the high frequency coil 2 by the high frequency power source, and a discharge is generated within the plasma generating tube 1. This discharge causes a polymerization reaction of the monomer gas, and a polymer film is formed on the sample 3.

However, in the above configuration, in addition to the polymerization reaction, etching action by ions occurs in the discharge region, so the side wall of the plasma generating tube 1 is also affected by the etching action, and as a result, the inside of the plasma generating tube 1 in the discharge state is affected by the etching action. However, in addition to the monomer gas components, the components of the inner wall of the plasma generating tube are added, resulting in a change in the components of the polymerized film.

An inert gas (for example, Ar) and a monomer gas are introduced into the plasma generation tube 6 through the gas inlet 8 under a condition of less than 100 yen. If the monomer gas is easily dischargeable, it is not necessary to introduce an inert gas. The pressure inside the plasma generating tube 6 after introducing the inert gas and the monomer gas may be set to any value as long as discharge is possible, but the pressure is 1, OX 10-'
Ton ~2.0 Ton is suitable. After the above settings, when high frequency power is supplied to the high frequency coil 7 wound around the plasma generating tube 6, a discharge is generated inside the plasma generating tube 6. Gas containing radical groups generated by this discharge is transferred from the lower end of the plasma generating tube 6 to the tape supply reel 9, the tape take-up reel 10, and the guide rollers 12 and 13.
, 14 and 15, the liquid is blown onto the surface of the tape-shaped magnetic recording medium 11 that is being wound around a guide post and traveling, and a polymeric film is formed on the surface of the tape-shaped magnetic recording medium 11.

However, even with the above configuration, the inner wall of the plasma generating tube 6 is subjected to etching action by ions, and the components in the discharge contain components other than the monomer gas, albeit minutely, as in the conventional example described above. This method has had the problem of having an adverse effect on the polymer film formed. This tendency becomes more noticeable when a monomer gas with a large etching effect is used. For example, when using a fluorine-containing gas as a monomer gas, octafluorocyclobutane (04F
8) Tetrafluoromethane (CF4) has a larger effect than CF4.

The operation of the thin film forming apparatus having this configuration will be described below. The setting of the device and its operating principle are exactly the same as in the prior art example described above. High frequency power is supplied to a plasma generation tube into which an inert gas (for example, Ar) and a monomer gas have been introduced through a high frequency coil wound around the plasma generation tube to generate an electric discharge.
