2" RF Plasma Magnetron Sputtering Coater for Non-Conductive Thin Films - VTC-2RF

Please email for lead time
Item Number: VTC2RF
Transported by LTL Freight (Truck)

VTC-2RF is a compact 2" single head RF Plasma magnetron sputtering system coating non-metallic, mainly oxide thin film. It integrates all components into one-floor stand cabinet, including RF power source, quartz vacuum chamber, vacuum pump, recirculation water chiller and film thickness monitor, etc. It is an excellent and cost-effective coater for coating thin film of non-conductive or oxide material in R&D.

Sputtering Target

Vacuum Chamber

  • Vacuum Chamber: 160 mm OD x 150 mm ID x  250 mm Height. made of high purity quartz
  • Sealing Flange: 165 mm Dia. made of Aluminum with high-temperature silicone O-ring
  • The stainless steel mesh cover is included for 100% shielding RF radiation from the chamber
  • Vacuum level: 1.0E-2 Torr with included dual-stage mechanical pump and 1.0E-5 Torr with optional turbopump

Sample Holder

  • The sample holder is rotatable and heat-able made of a ceramic heater with stainless steel cover
  • The sample holder size: 50 mm Dia. for 2" wafer max
  • Rotation speed is adjustable: 1 - 10 rpm for uniform coating
  • The holder temperature is adjustable from RT to 500°C Max with accuracy +/- 1.0 °C via a digital temperature controller.
  • 800- 1000ºC heating sample holder is available upon request upon request.
  • Optional vibration sample hold is available for power PVD coating. ( Pic 3 below )
  •         RF powder coating (optional)
Vacuum Pump Station

  • KF25 Vacuum port is built-in for connecting to a vacuum pump.
  • A vacuum pump with KF25 adaptor is required, but not included.. Please click the pic 1-2 to order separately.
  • Vacuum level: 1.0E-2 Torr with dual-stage mechanical pump and  1.0E-5 Torr with the turbopump
  • The 1 PPm ga purification system may be used to replace turbopump to get a more clean chamber.

Operation Instruction


Application Notes

  • This compact 2" RF magnetron sputtering coater is designed for coating oxide thin films on oxide single crystal substrates, which usually does not need high vacuum set-up
  • Please use > 5N purity Ar gas for plasma sputtering
  • For the best film-substrate adhesion strength, please clean the substrate surface before coating:
  • Ultrasonic cleaning (Click Pic #1 to order) with the following sequential baths - (1) acetone, (2) isopropyl alcohol - to remove oil and grease. Blow-dry the substrate with N2, then hot bake in vacuum to remove moisture
  • Plasma cleaning (Click Pic #2 to order) may be needed for surface roughening, surface chemical bonds activation, or additional contamination removal
  • A thin buffer layer (~5 nm), such as Cr, Ti, Mo, Ta, could be applied to improve adhesion of metals and alloys
  • For the best performance, the non-conductive targets must be installed with a copper backing plate. Please refer to the instruction video below (#3) for target bonding
  • MTI uses the Coaters have successfully coated ZnO on Al2O3 substrate at 500 °C (XRD profile in Pic #5)
  • DO NOT use tap water in a water chiller. Use DI water, distilled water, or anti-corrosive additives as coolant.
