When Adtec first started making RF Power products in 1990, the core concept was to make products that were world-leaders in ruggedness that the user could rely on, even in the toughest of environments. As critical dimensions and process windows shrink and the cost of down-time and scrapped product grows, it's even more important today than it was then to have RF products that can take the strain that industry demands.
At Adtec, we're confident that we've delivered on that promise - a confidence that allows us to give a two-year warranty as standard on all RF power supplies. It's a confidence our users share too,
as year-on-year Adtec brings more power to you.
Adtec RF products are used to enable plasma processes in semiconductor, flat-panel, data-storage, MEMS, solar, sputter and industrial coating applications. Over the years we've built up an enviable
track record of dependable product and support.
RF / Plasma Generators
Solid State linear amplified RF power supplies from 200W to 30kW in various frequencies give superior power control, superior reliability and less spurious noise.
Careful component choice, coupled with our own amplifier design means less strain on the amp and a higher MTBF. Stability in the amplifier also gives us greater scope to provide low-duty "microsecond" pulsed RF, and superb control even at 1W output. The 2-year warranty gives you peace of mind, and an idea of our confidence in our product.
Please note that we can supply custom spec units as well if they are within the below power and frequency ranges. So if you need something a bit different, please contact us!
RF Generator Model Overview
RF Matching Units
Adtec specialise in custom built matching networks. Each matching network is designed to the customer's exact specification to increase matching speed and accuracy. The matching sensor can be set to match from 1W, depending on customer needs.
Adtec matching unit power range specification is similar to the Adtec generators; ranging from 300W to 30000W. Depending on a customer's need the following items can be added:
Communication options that Adtec supply are:
How the matching unit works:
AC power on
Matching unit is idle and waits for RF power from the generator
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
Matching unit tunes to the lowest reflected power point - normally where network impedance (ZM)+
the reactor impedance (ZC) is 50ohm
The matching unit monitors the power signals and automatically re-tunes the system when ZC changes
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.
RF 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.
ACA-100 - 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:
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.
