  • Publication number: 20240077800
    Abstract: 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.

  • Patent number: 9995764
    Abstract: The present application relates to a method for avoiding damage when analyzing a sample surface with a scanning probe microscope, the method comprising the step of: detecting an electrostatic interaction between a charging of the sample surface and a measuring tip of the scanning probe microscope in the course of the approach of the measuring tip to the sample surface already at a distance from the sample surface which is greater than the distance of the measuring tip when analyzing the sample surface.
