Magnetron Sputtering Deposition in Perovskite Thin-film Battery
Industry
Applications
| Applications | Specific Purpose | Material Type |
| Perovskite thin-film battery | Transparent conducting layer | ZnO:Al |
Working Principle
Magnetron sputtering is to constrain and extend the motion paths of
electron by magnetic field, change the motion
directions of electron, increase the ionization rate of working gas
and effectively use the energy of electrons.
Magnetron sputtering has the following characteristics: rapid
deposition rate, high deposition efficiency, suitable for
large-scale application in industrial production; low substrate
temperature, suitable for the coating of plastics and
other heat resisting substrates; high purity of the prepared films,
good compactness, better film uniformity and strong
film-substrate cohesion; metal, alloy, oxide and other films can be
prepared; pollution-free.

Coating Sample
Process Steps
→ Place the substrate for coating into the vacuum chamber;
→ Roughly vacuumize;
→ Turn on molecular pump, vacuumize at top speed, then turn on the
revolution and rotation;
→ Heating the vacuum chamber until the temperature reaches the
target;
→ Implement the constant temperature control;
→ Clean elements;
→ Revolve and back to the origin;
→ Coating film according to process requirements;
→ Lower temperature and stop the pump assembly after coating;
→ Stop working when the automatic operation is finished.
