Classification: CPC H | IPC H

Claim 10:
11. The system set forth in claim 9 further comprising a processor and a memory coupled to the processor, the memory including a plurality of computer-readable instructions that, when executed by the processor, cause the system 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 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, apply a negative bias voltage to the electrically conductive structure proximate the region of the sample to alter a trajectory of the secondary electrons and repel the secondary electrons back to the sample surface.
