Hi,
My sample comprise of spinning AZ5214E resist on a composite film of =
Gold(30nm)-on-Chromium(5nm) thermally evaporated on SU-8.  I use AZ5214E =
resist to pattern Gold on underlying Chromium, which has been evaporated =
on SU-8 previously.  When lifting off the Gold  & AZ5214E resist using =
Acetone, how do I ensure that the Chromium is not lifted off as well as =
the unexposed SU-8 underneath the Chromium?
I have experienced the Acetone strips off Chromium and unexposed SU-8 as =
well.  This is undesired.

Thanks.

Jeffrey
