MANUFACTURING RESOURCES
Sputter Coating

Our thin film vacuum deposition tanks are constructed of stainless steel. They are cryo-pumped, clean, oil-free and capable of pumping to 1x10-7 torr. The main deposition drums may be heated or cooled. The deposition systems consist of planar sputtering cathodes capable of DC and pulsed DC magnetron sputtering. The sputtering supplies include arc suppression equipment to allow easy sputtering of normally difficult materials and reactive processes. Any or all of the systems can be operated simultaneously. Virtually any metal, alloy, semiconductor, metal oxide or nitride can be deposited in combination. Both deposition systems are equipped with quadrapole mass spectrometers and Ocean Optics UV/Vis spectrometers.

SYSTEM ONE can roll coat webs up to 24 inches wide with three cathode capability.
