An objectively and continuously process control of low-pressure plasma deposition techniques, such as PVD (Physical Vapor Deposition), is one of the real issues today. Aside from a visual examination of the plasma's light emission, sometimes the mass spectroscopy technique is used. Especially the mass spectroscopy is neither handy to operate nor the results are easy to interpret. Compared with this, the benefits of using the OES (Optical Emission Spectroscopy) and our fiber optics coupled TranSpec Spectrometers are obvious:

Schematic Gauge Setup

The plasma emission is captured inside the chamber through a special, flexible vacuum fiber optics cable, which is connected by a flange with another fiber light guide outside the chamber.

Note that, due to the use of these flexible vacuum fiber optics, the light emission can be observed also at different positions in front of the plasma!

The picture right beside shows a vacuum fiber feed-thru with a KF-50 flange and two FSMA adapters in order to connect a vacuum fiber inside the chamber and a regular fiber outside the chamber, which goes towards the TranSpec spectrometer.
