Working Principle
Magnetron sputtering principle: under the action of electric field, electrons collide with argon atoms in the process
of flying to the substrate at a high speed, ionizing plenty of argon ions and electrons, and then electrons fly to the
substrate. Argon ions bombard the target at a high speed under the action of electric field, sputtering lots of target
atoms,then the neutral target atoms (or molecules) deposit on the substrate to form films.

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.
