Home / Sputter Coaters / Sputter Coater K675X:

High Resolution, Large Sample Coater for Chromium & Other Metals

Complete 8 inch (200mm) wafers can be coated in The K675X Sputtering Coater System. The base system with twin gear rotating sample K675X Sputter Coater | Image Pop Upstage gives a progressive elliptical rotation for even sputtering desposition.

The K675X Coating System employs a magnetron target assembly which enhances the efficiency of the Sputtering process using low voltages, giving a thin and fine grain coating.

There are three such target assemblies in the K675X, positioned to give coating over a large diameter which, together with a rotating sample table, ensures even depositions. This method allows standard targets to be utilised, and avoids the necessity of special large profile targets.

The multi-target system is particularly useful in the semi-conductor wafer industry. It has a turbomolecular pump backed by a Rotary Vacuum Pump.

The integrated instrument panel and plug-in electronics maximise 'up-time' and, with user-friendly designs, ensures satisfactory multi-user discipline.

The sputtering parameters can be pre-set, including the gas bleed needle valve, which has electromagnetic valve back-up.

The independent Vacuum Pump is controlled by the Instrument throughout the fully automatic coating cycle. It can be used to Sputter Coat targets such as Gold, and also targets that may need pre-cleaning, or the removal of oxide layers, such as Chromium.

A shutter assembly is fitted as standard, which allows a Sputter Cleaning and the Sputter Cycle to be carried out while maintaining the vacuum.
