Problems solved by technology

However, generation of droplets is a problem in surface treatment such as film formation
If the droplet adheres to the surface of the object to be processed, the uniformity of the film formed on the surface of the object to be processed will be lost, and it will become a defective product of the film

Abstract

Plasma generation equipment having a plasma gun which can remove droplets mixed with plasma efficiently without reducing the effective amount of plasma generated by vacuum arc discharge and in which a droplet removing section can be constituted easily and inexpensively, and precision of surface treatment of films by high purity plasma can be enhanced. Periphery of the cathode (407) of a plasma gun is surrounded by an enclosure member (420) and a droplet remover (406) constituted by laying a plurality of droplet catching members (411) in multilayer is provided on the inside of the enclosure member (420). The enclosure member (420), the catching member (411) and a plasma traveling path (402) have no relation of connection with an arc power supply (409) and held in electrically neutral floating state.

Description

technical field [0001] The present invention relates to the generation of plasma by vacuum arc discharge in an arc discharge part set in a vacuum atmosphere, and is provided with cathode material particles (hereinafter referred to as droplets (droplets). ) The plasma generation device of the droplet removal part removed. Background technique [0002] Generally, in plasma, a technique of improving the surface properties of a solid by forming a thin film on the surface of a solid material and implanting ions is known. Films formed by plasma containing metal ions and non-metal ions are used to enhance the wear resistance and corrosion resistance of solid surfaces, and are used as protective films, optical films, transparent conductive films, etc. In particular, a carbon film using carbon plasma is highly useful as a diamond-like material film (called a DLC film) composed of an amorphous mixed crystal of a diamond structure and a graphite structure. [0003] As a method of gen...
