Abstract:
A method of operating a focused ion beam device having a gas field ion source is described. According to some embodiments, the method includes emitting an ion beam from a gas field ion source, providing an ion beam column ion beam energy in the ion beam column which is higher than the final beam energy, decelerating the ion beam for providing a final beam energy on impingement of the ion beam on the specimen of 1 keV to 4 keV, and imaging the specimen.
