Classification: CPC H | IPC H

Claim 0:
1. A method of processing a region of a sample, the method comprising:
positioning a sample within a vacuum chamber;
generating an ion beam with a focused ion beam (FIB) column;
focusing the ion beam on the sample and scanning 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, applying 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.
