Abstract
One embodiment described relates to a method of electron beam imaging of a target area of a substrate. An electron beam column is configured for charge-control pre-scanning using a primary electron beam. A pre-scan is performed over the target area. The electron beam column is re-configured for imaging using the primary electron beam. An imaging scan is then performed over the target area. Other embodiments are also described.
