The RTAS machines equipped with circular arc and cylinder sputtering deposition sources. Multiple combinations of DC sputtering, MF sputtering, arc evaporation and Ion source etc. All are available in one single machine, for a high flexibility in configurations to satisfy various applications. Especially for small components aesthetic coatings: jet black, copper, brass and chrome colors.
What is MF Sputtering?
Compared with DC and RF sputtering, Mid-Frequency sputtering has become a main thin film sputtering technique for mass production of coating, particularly for the film deposition of dielectric and non-conductive film coatings on surfaces such as optical coatings, solar panels, multiple layers, composite material film etc.
It is replacing RF sputtering due to it operated with kHz rather than MHz for a much faster deposition rate and also can avoid the Target poisoning during compound thin film deposition like DC.
MF sputtering targets always existed with two-sets. Two cathodes are used with an AC current switched back and forth between them which cleans the target surface with each reversal to reduce the charge build up on dielectrics that leads to arcing which can spew droplets into the plasma and prevent uniform thin film growth— which is what we called Target Poisoning.
