When Adtec first started making RF Power products in 1990, our goal and core concept was to be world-leaders in the design and manufacture of Radio Frequency Plasma Generation equipment.
We wanted to make products that were rugged and reliable – products that the user had full confidence in to deliver consistently, in the toughest of environments. As critical dimensions and process windows shrink, and the cost of down-time grows, it is more important than ever to have RF products that can take the strain the industry demands. This goal remains at the core of everything we do. We are confident that we are continuing to deliver – all RF power products come with a 2 year warranty as standard.
Adtec RF Products are essential facilitators of plasma processes across Semiconductor, Flat-Panel, Data-Storage, MEMS, Solar, Sputter and Industrial Coatings.
RF Plasma Generators
Solid State linear amplified RF power supplies give superior power control and reliability, with less spurious noise. Careful component choice, coupled with our meticulous amplifier reduces strain, greatly increasing the MTBF. The stability of the amplifier gives greater scope to provide low-duty, microsecond pulsed RF, with superb control at outputs as low as 1W.

1 | AC Power on | Matching unit is idle and waits for RF power from the generator |
2 | RF Power on | Matching unit's sensor picks up the RF power signal and activates the automatic tuning mode. By adjusting CLOAD and CPHASE it finds the ignition point of the plasma - normally the highest point of VPP throughput to the reactor |
3 | Plasma Ignites | Matching unit tunes to the lowest reflected power point - normally where network impedance (ZM)+ the reactor impedance (ZC) is 50ohm |
4 | Plasma ignites | The matching unit monitors the power signals and automatically re-tunes the system when ZC changes |
5 | RF Power off | Matching unit returns to idling |
Tuning parameters are stored internally on the matching unit and by using the AMV Control Software, parameters can be modified to change the matching speed, start point (via presets), matching range, and many more. For troubleshooting it is also possible to switch the system between manual and automatic setting. The AMV Control Software can be used to monitor the capacitor positions, forward power, reflected power, Vpp and Vdc (depending on customer requests) from the matching unit.
Presets and monitoring can be done via analogue control/RS232 control/Profibus (depending on customer request) and the AMV Control Software.
High Power RF Coaxial Switch Boxes
By including a Switch Box in your signal chain, it is possible to serve multiple processes with only one generator.
The switch serves as a pivot point, rapidly redirectly the RF from chamber to chamber

Measuring Devices
Adtec’s RF Measuring Devices are ideal for chamber measurements, tool calibration, troubleshooting and process development – our range will help deepen your understanding of your RF processes.
Portable and convenient chamber analyser
Trace display of forward and reflected wave power
Power Meters
As well as performing as a standard RF Watt-meter for general fab or lab use, our AW-series RF power measurement products for tool calibration, troubleshooting, or process development can add an extra dimension to your understanding of RF process. With digital and graphical (vs. time) display of forward and reflected power, traceable to international measurement standards, the data can be stored on internal memory, exported to your PC, then shared with colleagues in reports or archives.
RF Network analyser
The ACA-100 is a portable vector network analyzer for medium frequencies which enables you to do impedance measurements where ever you go. It supports the following three impedance measurement modes:
1. Normal impedance/frequency mode.
2. Real time impedance measurement mode at a specified frequency. (Data point)
3. Impedance/Period mode at a specified frequency. (Network)
The ACA-100 is manufactured to the same robust and durable standard of all ADTEC's products. All the functions on the ACA-100 are controlled via the software and it has no internal adjustments. There are no trim pots or caps inside. All the calibration is done with the following software procedure.
This reduces maintenance costs because you do not need to return the unit for a yearly calibration. You only have to do the normal network analyzer calibration steps before you start.
