Abstract
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.
