The TruPlasma VHF Series 3000 generators use an innovative platform concept that enables outstanding power density and meets the toughest process demands. The modular and purely water-cooled construction enables the output power to be scaled to up to 80 kW. These compact VHF generators are also very cost-effective and have a robust design.
This provides the best plasma process control for the present single and multi-level pulsing.
This means extremely flexible control of the generator ignition behaviour is possible.
Automatic frequency tuning for optimal interaction between the generator and the matchbox.
Excellent, reproducible process results thanks to highly precise digital frequency modulation.
The length of the RF cable does not need to be adapted when the process is changed, resulting in short setup times.
Reliable generator function even in the event of mismatch thanks to CombineLine technology.
Production of photovoltaic cells
There are numerous areas of application for tailored process energy in the photovoltaic field. Here, various plasma processes are used to add and remove materials, such as sputtering, PECVD and etching. The TruPlasma VHF Series 3000 generators can be adapted optimally to the respective process, with fast arc management allowing for stable control of the plasma. As a result, excellent process results and high productivity are guaranteed.
Various plasma processes are used to manufacture semi-conductors, from removal processes such as dry etching to zone refining in the production of pure silicon. TruPlasma VHF Series 3000 generators offer all of the conditions for a power supply that is stable and optimally adjusted to the respective process, ensuring that you achieve excellent, reproducible results.
Ideal for the coating of flat screens
The TruPlasma VHF Series 3000 generators are perfectly suited for plasma processes such as reactive-ion etching (RIE), atomic layer deposition (ALD), plasma-enhanced chemical vapour deposition (PECVD) and RF sputtering. These processes are used, among other things, for manufacturing semi-conductor components and micro-electromechanical systems (MEMS) as well as for coating flat screens and solar cells.

Flexible adaptation to the process
The modular platform concept of the TruPlasma VHF Series 3000 enables the output power to be scaled to up to 80 kW. Thanks to the CombineLine technology, the generator is also very robust, even in the event of a mismatch. Its wide frequency range, variable line voltage and cable length mean it can be adjusted for use in various applications and countries.
Extremely efficient and cost-effective
TruPlasma VHF Series 3000 RF generators are built with the latest semi-conductor technology with LDMOS power transistors. The highly integrated planar technology enables the highest power density levels with high energy efficiency, and a correspondingly reduced need for cooling capacity. As a result, this product family offers unparalleled cost-effectiveness in this frequency range and reduces the operating costs common on the market.
SystemPort enables closed loop control through the measurement of the RF signal directly at the input and output of the matchbox. All measured values are available to the RF generator. This means all the process parameters can be better monitored, the matchbox protected and early arc detection guaranteed. The entire RF system can therefore be controlled via a single generator interface.
Various options enable optimal adjustment of the VHF generator to your application.
The patented Auto Frequency Tuning solution enables simultaneous and fast frequency tuning and guarantees the optimal interaction between the generator and matchbox. Thanks to this patented technology, a local minimum is no longer an obstacle: the RF system is optimised, therefore guaranteeing the best process results and a high level of reproducibility.
The well-grounded arc management is the ideal module for optimised plasma process control. Targeted arc detection guarantees the highest productivity possible, whilst protecting the product and your system at the same time.
Flexible pulse shapes: the shape of the output signal can be adjusted to meet any process requirement.
The user-friendly TruControl Power control software enables the convenient start-up and secure monitoring of the RF generator or the entire TRUMPF RF system during the ongoing process.
By selecting suitable system components, you can perfectly adjust the VHF generator to your application requirements.
TruPlasma Match matchboxes ensure an optimal transfer of power from the generator to the plasma discharge. The matchbox can be operated independently or via an intelligent generator/matchbox connection, the so-called SystemPort.
This is comprised of an adapter for water connections, a HARTING AC supply set, a jumper for the the interlock function, and an adapter from LEMO EPL to BNC female (for clock and pulse sync plugs).
Master oscillators can be used to stabilise and optimise critical synchronous plasma processes. An integrated, digital frequency and phase synthesiser ensures excellent frequency and phase stability and supports the adjustment of the phase position with a very small increment. Various master oscillator designs for the frequency 13.56 MHz as well as different frequency combinations are available.
An RF switch supports the multiple use of an RF generator at various plasma process stations, for example, for providing power to sequential processes or on systems with various feed points. Various RF switches are available in two power classes and with 2, 3 or 4 outputs.
TRUMPF Hüttinger offers coaxial cables that are specifically designed for operation in 50-ohm systems for RF power transmission.
Perfectly matched: the TRUMPF RF System
Plasma processes behave like a complex, variable load, to which the power supply from the generator needs to be continually adjusted. Active matchboxes handle this task, ensuring precise adjustment to the optimal impedance of 50 ohms at all times. The result is a perfectly matched system solution, the TRUMPF RF System. The generator and matchbox can be easily integrated into your existing process environment via various interfaces, including EtherCAT. You can also gain an optimised system solution through an intelligent generator/matchbox connection, the so-called SystemPort.
