Abstract

PROBLEM TO BE SOLVED: To suppress the generation of particles and to easily produce thin films having high quality by rotating a film forming section where a substrate is arranged and magnetically floating the film forming section. SOLUTION: A revolving shaft 2 is passed through through-holes 10, 11 opened in the central axis position in the perpendicular direction of a frame 8 of the sputtering device. The top end of the revolving shaft 2 is fitted and fixed into the through-hole on the magnetic coupling side 3b of a magnetic coupling 3. The driving side 3a of magnetic coupling 3 is rotated together with the output revolving shaft 7a of a motor 7 to impart rotating force to the magnetic coupling side 3b of the magnetic coupling 3, i.e., the revolving shaft 2, by which the film forming section 1 is rotated at an optimum speed. The suction section 18 on the bore side rotating together with the revolving shaft is fixed to the revolving shaft 2 and a suction section 22 on the outside diameter side is installed to a holding member 9 projectingly disposed at the frame 8. Powerful magnetic attraction force is acted between these suction sections 18 and 22, by which the film forming section 1 is rotated in a magnetically floating state together with the revolving shaft 2.

However, in the above-mentioned conventional film forming apparatus, minute debris called particles are generated from the meshing portion between the gear 94 for driving the film forming section 100 and the uneven portion 95. Then, the particles are mixed into various thin films such as an ITO film and a black matrix film formed on the substrate 90, and there is a problem that the film formation quality is remarkably reduced. Also, wheels 93
The rotation caused by the contact between the film forming portion and the lower end surface 100a of the film formation portion and the upper surface of the rail 97 is accompanied by dynamic friction, so that a large amount of dust is generated and the problem of the particles is further increased. In addition, as the meshing portion between the gear 94 and the uneven portion 95 and the contact portion between the wheel 93 and the upper surface of the rail 97 or the lower end surface 100a of the film forming portion are worn down, the rotation of the film forming portion 100 is reduced. The roundness is reduced, so that, for example, a sputtering distance between a substrate (not shown), which is a film forming material, and a substrate varies, and there is a problem that a thin film having a uniform thickness cannot be formed. Therefore, an object of the present invention is to provide a film forming apparatus capable of obtaining a high-quality thin film with very little generation of particles and the like and ensuring a uniform thickness of the formed thin film.

According to the present invention, since the generation of particles is greatly suppressed, a high-quality thin film can be easily manufactured industrially, and its industrial utility is enormous. In addition, since the rotational force is transmitted to the film forming section via the magnetic coupling, a remarkable rotating mechanism such as a conventional meshing section can be omitted, and the roundness of rotation of the film forming section can be reduced. Is maintained satisfactorily over a long period of time to form a high-quality thin film having a uniform thickness. Further, since the rotation mechanism is hard to be worn down, the life of the rotation mechanism can be extended.

Next, an example of a magnetic levitation structure according to the present invention will be described. In the frame 8 shown in FIG. 1, as a magnetic action part for magnetically levitating the film formation unit 1, a suction part 18 on the inner diameter side which is fixed to the rotation shaft 2 and rotates together with the rotation shaft 2, An outer diameter side suction portion 22 fixed to the provided holding members 9 and 9 is provided. The inner diameter side suction unit 18
The same size ferromagnetic hollow disk yokes 16 and 17 (for example, made of SS400) are ring-shaped Nd-Fe-B magnets 15 (for example, HS37BH manufactured by Hitachi Metals, Ltd.).
45mm outer diameter x 35mm inner diameter x 10mm thickness. )
The rotating shafts 2 are passed through through holes formed at the center axis positions of the yokes 16 and 17, and the yokes 16, 17 and the rotating shaft 2 are fixed. The permanent magnet 15 is magnetized in the thickness direction, and the magnetic poles N and S are arranged in the vertical direction. The outer diameter side suction portion 22 is a hollow cylindrical ferromagnetic yoke (for example, made of SS400) 2 having the same dimensions.
Reference numerals 0 and 21 denote ring-shaped Nd-Fe-B magnets 19 (for example, HS37BH manufactured by Hitachi Metals, Ltd.) having an outer diameter of 100 m.
mx 65 mm inner diameter x 10 mm thick. ), And the upper end surface of the yoke 20 is
9 is connected. The permanent magnet 19 is also magnetized in the thickness direction, but its magnetic poles N and S have polarities opposite to the vertical magnetic poles of the permanent magnet 15. With this configuration, the upper yoke 16 on the inner diameter side has an S pole, and the upper yoke 20 on the outer diameter side has an N pole. The lower yoke 17 on the inner diameter side has an N pole, and the lower yoke 21 on the outer diameter side has an S pole. Between the upper yokes 16 and 20, and the lower yokes 17 and 2
Since the distance x with respect to 1 is set to 3 mm, a strong magnetic attraction acts between the suction parts 22 and 18 via this distance x. Under the film forming conditions, the film forming unit 1 includes the rotating shaft 2
The magnetic levitation force is given by the suction part 22 supported by the frame 8 via the space x and strongly sucking the suction part 18. The weight of the forming part 1 is canceled. here,
The distance x is 0.05 to 15 mm, preferably 0.2 to
It is desirable that the distance be appropriately set within a range of 5 mm. That is, if the thickness is less than 0.05 mm, the rotation of the film formation unit 1 is difficult to be smooth, and if it exceeds 15 mm, the magnetic attraction force is insufficient and the film formation unit 1 is hardly magnetically levitated.

According to the configuration shown in FIG. 1, the rotating mechanism of the film forming unit 1 is composed of the suction unit, the rotating shaft, the magnetic coupling, and the motor. Particles are prevented from entering the thin film formed on the substrate 90. In addition, since the rotating mechanism of the film forming unit 1 does not have a remarkable wear portion, the roundness of rotation of the film forming unit 1 is suppressed from being deteriorated with use, and a film product having a uniform thickness is manufactured. can do.

In FIG. 2, instead of the bearings 5 and 6, the lower end of the rotating shaft 2 is received by the pivot bearing 36, thereby suppressing the lateral runout of the film forming unit 1 during rotation. Also in this case, since the film formation unit 1 is in the magnetic levitation state, the generation of particles from the receiving surface of the pivot bearing 36 is extremely reduced.
