The installation of the matching network is virtually plug-and-play with our 5000W RF power generators.



Equipped with microprocessor-controlled stepper motor drives and advanced fuzzy logic tuning algorithms, the matching network rapidly transforms plasma impedances to 50 ohms to maximize power transfer to the process chamber and provides greater consistency and accuracy than traditional analog-based tuning methods. The result is optimized RF power to semiconductor, solar, FPD, and MEMs manufacturing plasma processes, including etch, PVD, PECVD, HDPCVD, ALD and chamber clean applications.
