I am looking for information on how to fix an issue I have with our
Perkin Elmer sputter tool. The system was working reasonably, but
now when we run the system there is alot of arcing. It is not
related to the target material or if we use a different target
position. At 100 W there is no arcing and once we go above that,
normally we use 700 W with this system for deposition of HfOx, we
observe the arcing issue. This is not a continuous arc, but very
sporadic events and has been leaving visible damage to the dark
shields and the chamber walls. I have cleaned the dark shields,
chamber wall, and sample stage with sandpaper and wipe all the
surfaces with solvents, but that did not seem to have an affect on
the arcing issue. <br>
<br>
This tool has also had a long issue with RF leakage effecting the
mass flow controllers and RF tuning unit. Past lab users have tried
to ground all the instruments that were effected but with minimal
improvement.<br>
<br>
Any information or help would be greatly appreciated.<br>
