Description

technical field

[0001] The invention relates to the technical field of plasma chemical vapor deposition, in particular to a microwave plasma vacuum coating device and a use method. Background technique

[0002] Plasma Enhanced Chemical Vapor Deposition PECVD: It uses microwave or radio frequency to ionize the gas containing the constituent atoms of the film to form plasma locally, and the plasma is very chemically active and easy to react, depositing the desired film on the substrate . In order to enable the chemical reaction to proceed at a lower temperature, the activity of the plasma is used to promote the reaction, so this CVD is called plasma-enhanced chemical vapor deposition (PECVD). Experimental mechanism: The gas containing the constituent atoms of the film is locally formed into plasma by means of microwave or radio frequency, and the plasma is chemically active and easily reacts to deposit the desired film on the substrate.
