Hello Everyone

I have this thin ZnO thin film foil and I want to cut it to get mm
scale, for example 7 mm x 7 mm without damaging its surface
smoothness. So the two important factors are:
1. Surface should stay smooth. No damage to the surface.
2. Also I don't want to deform the surface when I cut it.
I really appreciate if you give me some suggestions. Thank you very
much. Let's support MEMS-TALK.
