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:
• Ultrasonic cleaning 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
• Plasma cleaning 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 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
• TMAX supplies single crystal substrate from A to Z 
• TMAX 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 tester.

• 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
