Beschreibung
Zusammenfassung:	A method for removing particles from a mask system for a projection exposure apparatus, including the following method steps: detecting the particle in the mask system, providing laser radiation, and removing the particle by irradiating the particle with laser radiation. The wavelength of the laser radiation corresponds to that of used radiation used by the projection exposure apparatus.
