Hi: I am new to ebeam technology but have a MEMs application where I'd like to use ebeam lithography. I'd like to define a pattern about a micron wide at the narrowest point, develop it by wet developer, then do some metal depositions and then remove the resist by a thermal treatment instead of by a wet lift off step. In fact I need to avoid any chemical treatment at this stage because of a sensitive material layer. Thermal stability of all material layers is, however, no problem. I've heard of some burn-off type resists but don't know the details. I think PMMA doesn't quite burn off completely. Can anyone suggest anything? Thank you, Gareth Hougham (914) 945-1946
