(Summary description)Can plasma treatment equipment enhance ionization? What are some good methods: The ionization phenomenon in plasma processing equipment is closely related to the movement of electrons, and enhanced ionization also has a great impact on the effect of plasma processing. Then, how can the ionization effect of plasma processing equipment be enhanced? There are two existing proof methods, one is obtained through the reasonable coordination of the time between the electron and the field position in the elastic collision, and the other is obtained through the "surfing" effect.  For the mechanism of electron acceleration, the ideal condition is that when electrons collide with argon atoms elastically and turn in the electric field, the speed and energy of the electrons will increase; if the above conditions are met, the electrons can obtain ionization energy, even if the electric field strength is very weak. , It can also get ionization energy. In this mechanism, the ideal range of electric field frequency is usually around several thousand MHz. Some scholars have extended this mechanism. They believe that the secondary electrons emitted from the wall and the cathode enter the photodischarge area after being accelerated, and become an additional source of electrons, which is a phenomenon of secondary electron multiplication. When the secondary electrons are released, if the electric field is reversed to achieve the same phase, the ionization can be effectively enhanced. The impulse effect is another evidence mechanism of ionization enhancement. It is generally believed that under the action of a high-frequency alternating electric field, the "impulse" phenomenon of electrons at the interface of the electrode sheath of the plasma treatment equipment can effectively enhance ionization, which is generally expressed as plasma The sheath voltage and sheath of the body treatment equipment fluctuate continuously. Existing calculations and demonstrations show that electrons obtain energy through sheath oscillation, and "surfing" electrons will have a positive effect on the ionization process.
