Thick resist

[Uma Krishnamoorthy]

Does anyone have much experience using thick resist (SPR220-7) as a mask
for oxide etching on the amtetcher? If so, any suggestions on
preprocessing  my wafers before the etch step? 

Also, I need to etch a very thin layer of oxide (~500A) on my wafer. With
Sharleen leaving, I cannot get trained on the equipment either.  Is anyone
running a similar program that I could piggyback on anytime soon? 

Thanks

Uma
