Problems solved by technology

The gas homogenizer is installed on the side of the upper electrode and the lower electrode and does not surround the substrate, so the gas supplied to the vacuum chamber through the gas homogenizer will inevitably affect the uniformity of the gas due to its installation position
In addition, uniform air intake through the gas homogenization device not only increases the cost of producing diamond-like carbon films, but also the gas homogenization device will occupy the capacity of the vacuum chamber, thereby reducing the production efficiency of diamond-like carbon

Abstract

The invention mainly provides a gas inlet system of a coating device. The gas inlet system is used for the coating device to provide coating gas for at least one product to be coated, the coating device is used for carrying out diamond-like coating on the product to be coated, and the gas inlet system of the coating device comprises at least one stand column, and the coating device provides coating gas for the surface of the product to be coated through the stand column.

Description

technical field [0001] The invention relates to an air intake system and an air intake method of a coating device, in particular, the invention relates to an air intake system capable of improving coating uniformity. Background technique [0002] Diamond-like carbon film has high hardness, low friction coefficient, high wear resistance and good chemical stability, thermal conductivity, electrical insulation, light transmission and biocompatibility, as a new functional film material in mechanical wear-resistant coating , optical windows, microelectromechanical systems (MEMS) and semiconductor materials have broad application prospects. [0003] The diamond-like material is an amorphous structure of carbon, and the preparation of the diamond-like film needs to obtain the metastable sp in the non-equilibrium process 3 and sp 2 bonded carbon. The main methods include physical vapor deposition, chemical vapor deposition and liquid phase preparation techniques. [0004] Among ...
