Fast and easy sample preparation with reduced curtaining artifacts using a P-FIB

The present methodology proposes to reduce curtaining artifacts using a plasma-FIB when milling relatively deep trenches. Finally, the methodology is very fast (<;1 h), simple to set up and can be automated. Its purpose consists in eliminating or reducing the origin of curtaining artifacts by judicious milling. This methodology can advantageously replace the rocking method presented in the literature.
