DX Series RF Matcher for IND

DX Series Matcher is designed for transferring a maximum power from a source RF power generator to a load system.

Generally a load system will be the plasma application that have many different, changed impedance and while the system is igniting an gas in plasma condition by RF power generator the system impedance are changing. Under this conditions, RF power generators are very difficult to transfer efficient source power to target load application due to un-matching system impedance.

The design are measuring/tracking drifted impedance between a load system and RF power source of generator and match impedances between both. so automatically to minimize a reflect power of source RF power, this design efficiently make transferring maximum power to a load applications from RF generators.

TTMS(Tunable Termination Matching System)

TTMS is a technology that controls the process by influencing the plasma inside the facility by connecting variable capacitors in series to the RF ground underneath the plasma facility.

RFPT’s TTMS offers the latest RF power semiconductor technology and outstanding operating features making them leading edge products. To protect the TTMS circuit, a temperature sensor called safety eye was applied, and a 9-pin D-SUB interface was also applied for communication. Which is used in various ways, such as deposition, etcher, cleaning, Asher, Atmospheric pressure, and Sputter systems.
