Abstract
A system and method for reducing ion contamination in an object, the ion contamination introduced by a contaminating ion beam milling step. The system includes means for defining a suspected ion contaminated area; and means for removing the suspected ion contaminated area by a non-contaminating process, which usually involves directing an electron beam towards the removed area while allowing the beam to interact with additional material. The method includes the steps of defining a suspected ion contaminated area; and removing the suspected ion contaminated area by non-contaminating process.
