Hello p5000 users,
 I want to use p5000 to etch 1.5 um of thermal oxide on a wafer that has
metal features on its backside. I am concerned about whether this might
cause scratches on the backside. If you have tried something like this
before, I would appreciate your sharing your experience with me.
