TruPlasma Bipolar Series 4000 (G2.1)

Optimal coating quality results

Latest generation of bipolar pulse generators

The process power supplies of the TruPlasma Bipolar Series 4000 (G2.1) were specifically developed for plasma-assisted coating using PVD, PECVD or reactive sputter processes. Thanks to their flexible output signals and sophisticated ARC management, they deliver excellent results when manufacturing solar cells and semi-conductors, when applying decorative and wear-resistant layers and when coating architectural glass.

Extremely low ARC energy

Fully digital arc management for the highest coating quality and productivity.

Configurable wave forms

Simple adjustment to various processes by varying the output signal.

One generator, numerous applications

DC, pulsed DC and bipolar: save on costs thanks to diverse settings.

Integrated water cooling

No external components are required, meaning it only requires a small amount of space.

First-rate power supply

Typical areas of application include semi-conductor and photovoltaics production, coating architectural glazing and manufacturing decorative and wear-resistant coatings of the highest quality. PVD and PECVD processes, in particular, are used for this.

Perfect coatings, high productivity

Completely digital arc management with very low arc energy ensures high coating quality and deposition rates. Even in demanding reactive processes, the TruPlasma Bipolar Series 4000 (G2.1) always guarantees a uniform process power supply and thus a stable plasma condition.

More flexibility, lower costs

Adjustable wave forms mean that you can very easily adjust the TruPlasma Bipolar Series 4000 (G2.1) generators to suit a variety of process requirements. Thanks to the flexible selection of the output signal (DC, pulsed DC or bipolar), they can be used with versatility, thereby helping to reduce your total cost of ownership (TCO).

Everything in a single housing

No external components are needed thanks to the water cooling, which is fully integrated in the environmentally-protected generator housing.

PVD Power

The user-friendly, multilingual PVD Power software offers you numerous operation, configuration, and diagnosis options for optimising process quality and effective error correction: display of actual values for all relevant process parameters as well as warnings and alarms, specification of target values by the operator, as well as recording and visualisation of important operating parameters with high temporal resolution (oscilloscope function).

By selecting from a variety of system components, you can optimally adjust your bipolar pulse generator to your system environment.

Mains cable

Various cable and connector designs are available for different connection standards.

It depends on the form: bipolar sputtering
Two characteristics of bipolar power supplies are presented in this article: (i) a wide pulse frequency range of up to 100 kHz and (ii) an additional brake time between the positive and negative half-wave of the square wave shape of electricity and voltage.

Sine or square wave
Since the introduction of dual magnetron sputtering (DMS) for highly insulating layers, it is possible to choose between a square wave pulse and sine wave power supply.
