(Summary description)According to the nature of gases, plasmas can be divided into the following two types: Gas and the gas plasma: gaseous plasma according to their chemical properties of the gas used when different can be divided into two categories, lively and inert gas gas, inert plasma such as argon (Ar), nitrogen (N2), nitrogen fluoride (NF3) is used, carbon tetrafluoride (CF4), air, gas plasma such as oxygen (O2), hydrogen (H2), etc., the reaction mechanism of different kinds of gas in the process of cleaning, lively plasma have bigger influence on the chemical reaction. Because of the different nature of gases, the pollutants used for cleaning them must also have different choices. If one gas permeates into another or more gases, the mixture of these elements will produce the etching and cleaning effects we want. By using the ions or highly active atoms in plasma, the surface pollutants are smashed apart or formed into volatile gases, which are sent out through the vacuum system to achieve the purpose of surface cleaning. At low pressure in a high-frequency electric field, gas molecules, such as oxygen, nitrogen, methane, water vapor, in a glow discharge, will break down the accelerating atoms and molecules. When the generated electrons are accelerated in the electric field, they can obtain high energy and collide with the surrounding molecules or atoms, so that the molecules and atoms are reexcited by the electrons, but they are in the excited state or ionic state. At this time, the existence state of the matter is the plasma state. In addition to gas molecules, ions and electrons, there are electrically neutral atoms or groups of atoms in a plasma, which are excited by the state of energy (also known as free radicals) and the light emitted by the plasma. Among them, the length and energy of the wave play an important role in the interaction between the plasma and the material surface. In the plasma cleaning process, nitrogen as an inactive gas, mainly as a non-reactive gas, nitrogen plasma treatment can improve the hardness and wear resistance of materials. Sometimes, nitrogen also ACTS as an active gas, forming ammonia compounds. In many cases, plasma cleaner manufacturers use nitrogen or use it as an inactive gas.
