- Actually ion-milling is the last step of the thinning process. Also,
- once a sample has been properly thinned and used and then stored for
- a while, one has to ion-mill it again before reusing, that way get
- rid of the oxides and/or dirts that have accumulated during storage.
-
- However, inevitably one has to go through a sequence of polishing
- processes before s/he can put the sample in the ion-mill.
