  This paper addresses issues related to cracking and blisters in deposited
films encountered in a lift-off process with electron beam evaporation and a
bilayer PMMA resist system. The impact of charged particles, i.e. electrons and
ions, is investigated using an electron beam evaporation chamber equipped with
ring-magnets and a plate electrode placed in front of the sample. By replacing
the plate electrode with a hollow cylinder, the modified evaporation setup
utilizing passive components allows a complete elimination of resist shrinkage
and blistering yielding near perfect deposition results for a large variety of
different materials.
