Dear Colleagues, I am looking for a thin resist (300nm), resistant to acetone and trichloroethylene, that can be easily etched with O2 plasma. I plan to use it in a bilayer configuration PMMA/resist. I will transfer patterns defined by e-beam lithography by etching the resist with O2 plasma. All the process must be made at low temperature (T<140°C). I already tried Su 8, but it was too rough after O2 plasma for my process. Does anyone ever heard about such a resist? I would be very pleased for any suggestion, Thanks a lot, Olivier Boulle
