Fourth state: Reaction between plasma and soli:

Plasma is a kind of hot gas composed of disordered moving electrons, ions, atoms and molecules. It widely exists in the universe and is often regarded as the fourth state of matter in addition to solid, liquid and gaseous state. The seemingly "mysterious" plasma is actually a common material in the universe that forms the interior of stars, lightning. In the study of plasma, a team from the Institute of Theoretical and Astrophysics at Keele University has discovered a surprising new effect: that the electronic properties of solid materials, such as electrical conductivity, can be changed in a controlled, extremely fast and reversible way by plasma shocks. The results are in the journal Physical Review Letters.

For more than 50 years, scientists in plasma physics and materials science have been studying the interfacial reactions between plasma and solids. Now people have mastered the use of electric field and magnetic field generation to control the plasma, developed a lot of plasma related high-tech, plasma surface treatment equipment, such as: plasma processor, plasma cleaning machine, etc. The interaction reaction between plasma and solid is that the plasma interacts with the surface of the object through its own active components, so as to realize the modification, cleaning, photoresist ashing and other purposes.

With the progress of science and technology and the development of The Times, plasma technology has ushered in a broad stage. Plasma has broad application space in automobile manufacturing industry, mobile phone manufacturing industry, medical industry, electronics industry, semiconductor packaging industry, new energy industry, LCD display screen industry, FPC/PCB industry, textile printing and dyeing industry and many other industries. Plasma surface treatment is widely used in metal, microelectronics, polymers, biological functional materials, low temperature sterilization and pollution control and other fields. Compared with traditional methods, plasma surface treatment has the obvious advantages of low cost, no waste, no pollution and so on. Meanwhile, it can obtain the treatment effect that traditional chemical methods cannot achieve.

Shenzhen Sing Fung Intelligent  Manufacturing Co., Ltd. Is a leading brand of plasma technology high-tech enterprises, for the various industries to provide professional, efficient, energy saving, environmental protection plasma treatment solutions.
