Methods and systems for process monitoring using x-ray emission

摘要

Systems and methods for process monitoring based upon X-ray emission induced by a beam of charged particles such as electrons or ions include a system and method for process monitoring that analyze a cavity before being filled and then analyze emitted X-rays from the cavity after the cavity has been filled with a conductive material. Also included are system and methods for process monitoring that apply a quantitative analysis correction technique on detected X-ray emissions.
