Beschreibung
Zusammenfassung:	Methods and systems for photomask defect dispositioning are provided. One method includes directing energy to a photomask and detecting energy from the photomask. The photomask is configured for use at one or more extreme ultraviolet wavelengths of light. The method also includes detecting defects on the photomask based on the detected energy. In addition, the method includes generating charged particle beam images of the photomask at locations of the detected defects. The method further includes dispositioning the detected defects based on the charged particle beam images generated for the detected defects.
