Rotating molybdenum target
Molybdenum target is very useful. Its raw material is in powder form. In the hands of the master, through a series of operating methods, it is turned into molybdenum target handicrafts, which continuously improves the quality of life.
The composition of rotating molybdenum target:
1. The rotating target is a magnetically controlled target. The target is made into a cylinder with a stationary magnet inside, which rolls at a slow speed.
2. The sputtering target is used for magnetron sputtering coating. Sputtering coating is a new physical vapor coating (PVD) method.
3. Add an orthogonal magnetic field and an electric field between the sputtered target (cathin) and anode, and fill the high vacuum chamber with the required inert gas (usually Ar gas). Under the effect of the electric field, the Ar gas ionizes into positive For ions and electrons, a certain negative high voltage is added to the target. The electrons emitted from the target are affected by the magnetic field and the ionization probability of the working gas increases, forming a high-density plasma near the cathode. The effect of Ar ions on the Lorentz force The sputtered atoms on the target follow the principle of momentum conversion and fly away from the target surface with high kinetic energy toward the substrate to deposit films.
4. Tungsten and molybdenum product manufacturers stated that rotating targets are widely used in solar cells, architectural glass, automotive glass, semiconductors, flat-panel TVs and other fields.
