Problems solved by technology

Therefore, the opportunity to carry out the film-forming process with a full load of substrates in the vacuum chamber of the physical deposition apparatus is reduced, and the productivity is reduced.
[0013] In addition, in the AIP device disclosed in Patent Document 4, the anode of (1) captures the vapor from the cylindrical arc evaporation source and prevents the vapor from going to the substrate, causing a decrease in the film formation rate, that is, a decrease in productivity. reduction of
In addition, the trapped vapor accumulates on the anode, and the deposited vapor (film material) peels off to cause defects in the film
Therefore, in the AIP apparatus using the anode of (1) above, it is necessary to frequently clean the anode, which causes a decrease in productivity.
In addition, although the anode of (2) does not capture vapor like the anode of (1), it is difficult to control the position of the arc spot of the arc discharge when the length of the cylindrical arc evaporation source is large. , cannot be said to be practical
Therefore, the anode of (1) above is used in an actual device, thereby causing a decrease in productivity

Abstract

This vacuum film formation device forms a film on a base material and is provided with a vacuum chamber, an evacuation means for evacuating the inside of the vacuum chamber, a plurality of rotating holders that in a rotating state hold the base material on which a film is to be formed, and a revolving mechanism that causes the plurality of rotating holders to revolve around revolution axes that are parallel to the rotation axes of each rotating holder. The plurality of rotating holders is divided into a plurality of groups and electrical power is provided to the rotating holders so as to make the electric potential different for each group. For example, each group temporally alternates between a state in which the group becomes a negative electrode and operates as an action pole that fulfills the primary role in glow discharge plasma generation and a state in which the group operates as the opposing pole.

Description

technical field [0001] The present invention relates to a vacuum film forming method (for example, including ion plating (including AIP method), sputtering method, plasma Bulk CVD method and their combination) vacuum film forming device. Background technique [0002] Since the 1980s, in order to improve the life of cutting tools, hard coatings such as TiN and TiAlN have been formed on substrates by vacuum film-forming methods such as AIP (Arc Ion Plating) or sputtering. In addition, in recent years, for the purpose of improving the wear resistance and burn resistance of the surface, CrN and DLC (Diamond-Like-Carbon : Wear-resistant coating (coating) such as diamond-like carbon). [0003] The equipment for performing such vacuum film formation aims to uniformly process a large number of substrates (members) at one time. The film is formed with the voltage for the purpose of plasma generation or film quality adjustment. [0004] For example, Patent Document 1 discloses a f...
