Claim 15:
16. A non-transitory computer-readable memory comprising a plurality of computer-readable instructions that, when executed by one or more processors, cause the processors to:
position a sample within a vacuum chamber;
generate an ion beam with a focused ion beam (FIB) column;
focus the ion beam on the sample and scan the focused ion beam across the region of the sample thereby generating secondary electrons that are ejected from a surface of the sample within the region; and
during the scanning, apply a negative bias voltage to an electrically conductive structure proximate the region to alter a trajectory of the secondary electrons and repel the secondary electrons back to the sample surface, wherein the electrically conductive structure is one of a gas injection nozzle, a voltage pin or a nano-manipulator.
