RF Match Tuning

An RF Match matches the impedance of an etch chamber to your RF Generator. If these two devices are not matched correctly…bad things happen. When RF travels of the surface of conductors, this is called “The Skin Effect”. If you are not matched properly, RF will radiate to place you do not want it to (trust us on this one).

What Are the Possible Outcomes of Improper RF Match Tuning?

  • Blowing up your expensive RF Generator because of too much reflective power is coming back at the RF Generator. Yikes.
  • Lower etching and ashing rates which can scrap your expensive production wafers. Ugh frustrating.
  • You can have all kind of strange noise problems on all your wiring which can wreak havoc on your machine giving you strange readings on vacuum pressures. Not good.

How Does SemiGroup Ensure My RF Match is Working Properly?

After Semigroup refurbishes your RF Match to OEM standards, we use a rigorous testing process to ensure your equipment is safe and in excellent working condition:

1. Test RF Match under factory loads
