• Air inlet valve is installed for vacuum release

Vacuum Pump Station

• A mobile pump station is included. The sputtering coater can be placed on top of station
• High-speed turbo pump at speed 80L/S is combined with a two-stage mechanical pump (220 L/min) for max vacuum level and faster pumping speed
• Standard vacuum level connected with chamber : < 4.0E-5 Torr. .  (1.0E-6 Torr with chamber baking )
• Optional at extra cost
• If choose a 150L/S high speed turbo pump, vacuum can reach 10-6 torr  with chamber  ( 6x10-7 torr with baking)
• For the ultra-high vacuum upto 10^-7 torr, a getter pump (100L/s H2 & O2) is needed in addition to the turbo pump. Please consult our engineers for detailed customization.

Application Notes

• A two-stage pressure regulator (not included) should be installed on gas cylinder to limit the gas output pressure below 0.02 MPa for safe usage
• In order to remove oxygen from the chamber, we suggest you to use 5% Hydrogen + 95 % Nitrogen to clean the chamber 2-3 times, which can reduce oxygen level to < 10 ppm
• Please use > 5N purity Argon gas for plasma sputtering. Even though 5N purity Ar usually contains 10 - 100 ppm oxygen and H2O depending on the supplier. MTI suggest you to use gas purification device to purify gas before filling in.
• For best performance, the non-conductive targets must be installed with a copper backing plate. Please refer to the instruction video below for target bonding
• TMAX supplies single crystal substrate from A to Z
• TMAX Sputtering Coaters have successfully coated ZnO on Al ₂ O ₃ substrate at 500 °C
• 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 / DC 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
