IONIX® 4'' UHV Circular Sputtering Source

The IONIX® IX4U magnetron sputtering source has a target diameter of 101.6 mm (4'') and can be used with non-ferromagnetic targets varying from 4 -10 mm thickness. The magnetron features indirect cooling of the target, discrete target clamping and a sliding anode allowing easy adjustment of the dark space gap when varying target thickness.

The IX4U has a fully UHV compatible design utilizing only metallic seals and construction materials with low-outgassing rate. The IX4U is bakeable up to 200°C with its SmCo magnet array inserted and can be in DC, AC, RF and pulsed operation.

Optionally a version with a magnet array for ferromagnetic target materials ( Ni 4 mm, Fe 2 mm thick) is available. The IX4U can be either internally mounted via DN63CF interface or directly flange mounted on a DN160CF flange.
