Sputtering Target

• Target size requirement: 2" diameter x 1/4"thickness Max
• One Cu target (2" dia. x 3mm t) is included for the demo test.
• Al2O3 ceramic target  Recommend Coating Method
• Optional 2" sputtering targets (with backing plate) are available upon request at extra cost.

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

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.
