Plasma surface treatment is to ionize the gas into plasma by applying sufficient energy to it. The "active" components of plasma include: ions, electrons, atoms, active genes, etc. Plasma treatment is to use the properties of these active components to treat the surface of the sample, so as to achieve cleaning, modification, etching and other purposes.
The structure of the online chip vacuum plasma cleaning machine is mainly divided into five components: control system, excitation power system, vacuum chamber, process gas system, and vacuum pump system.
（A）Control System:The role of the control system is to control the operation of the entire on-line vacuum plasma cleaning equipment and the protection of the overall system.
（B）Excitation power system:The generation of plasma requires high voltage excitation, and the online chip vacuum plasma adopts RF power supply, power 0-600W, frequency 13.56MHZ.
（C）Vacuum cavity:The vacuum chamber is made of aluminum alloy (stainless steel chamber can be customized)
（D）Process gas system:Standard two-way process gas, argon/oxygen (can be customized)
（E）Vacuum pump system:The vacuum pump group adopts oil pump, and the vacuum pumping speed is one of the important factors to determine the working efficiency of a vacuum plasma cleaning machine. The speed of vacuum pumping mainly depends on the vacuum pump.
