What are the Sample Preparation Steps for SEM?

Sample preparation for SEM is somewhat different:
Fixation: Similar to TEM to preserve the structure.
Dehydration: Using a critical point dryer to prevent shrinkage.
Mounting: Attaching the sample to a stub using conductive adhesive.
Coating: Sputter-coating the sample with a thin layer of metal, usually gold or platinum, to improve conductivity.
