[labnetwork] Dektak 6m profilometer

[Dennis Culver]

 Hello Brian,Although I do not work on/with the Dektak 6M product, I do work on older Veeco/Sloan Technology Profilers.  The most likely issue if those erroneous step heights are the same magnitude is an open/bent pin on the A/D convertor or a bad buffer IC on the output data bits of that A/D converter.  Use ESD precautions when poking around with the electronics so no more issues are created from mishandling!

  Hello,
We are having an issue with our Dektak (Veeco) 6M.  Does anyone here know anyone with expertise working on these units?  It's showing abrupt steps on a patternless wafer.  
Thanks,Brian
