Zusammenfassung:	The present application relates to a method for removing a particle from a photolithographic mask, including the following steps: (a) positioning a manipulator, which is movable relative to the mask, in the vicinity of the particle to be removed; (b) connecting the manipulator to the particle by depositing a connecting material on the manipulator and/or the particle from the vapor phase; (c) removing the particle by moving the manipulator relative to the photolithographic mask; and (d) separating the removed particle from the manipulator by carrying out a particle-beam-induced etching process which removes at least a portion of the manipulator.
