VTC-3RF is a three head 1" RF Plasma magnetron sputtering system designed for non-metallic thin film coating, mainly for multilayer oxide thin films. It is the most cost-effective coater for researching in the new generation of oxide thin films. DC magnetron sputtering option is available upon request for metallic film deposition, enabling three DC, one RF / two DC, and two RF / one DC sputtering head configurations.

Operation Instruction


Application Notes


  •      •  This compact 1" 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

  •      •  A two-stage pressure regulator (not included) should be installed on the gas cylinder
            to limit the output pressure of gas to below 0.02 MPa for safe usage. Please use >
            5N purity Ar gas for plasma sputtering

  •      •  For the best film-substrate adhesion strength, please clean the substrate surface
            before coating:

    •          º  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 absorbed moisture

    •          º  Plasma cleaning (Click Pic #2 to order) may be needed for surface roughening,
                   surface chemical bonds activation, or additional contamination removal

    •          º  A thin buffer layer (~5 nm), such as Cr, Ti, Mo, Ta, could be applied to improve
                  adhesion of metals and alloys

  •      •  For 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 supplies single crystal substrate from A to Z (Click Pic #4 to order)

  •      •  MTI RF Plasma Sputtering Coaters have successfully coated ZnO on Al2O3 substrate
             at 500 °C (XRD profile in Pic #5)

  •      •  Test the flexibility of the thin film/coated electrode with EQ-MBT-12-LD mandrel bending
    . (Click Pic.6 for detail.)

  •      •  HIGH VOLTAGE! Sputtering heads connect to high voltage. For safety, the operator
            must shut down the RF generator before sample loading and target changing operations

  •      •  DO NOT use tap water in water chiller. Use coolant, DI water, distilled water,
            or anti-corrosive additives with water
