Abstract:
1. A method for removing a particle attached on a surface of a sample to be cleaned, the method comprising: providing nano tweezers having a pair of arms with respective gripping sections that are openable and closable to open and close the tweezers, and providing an adhesion member placed separately from the sample to be cleaned; wherein moving the arms of the nano tweezers toward the surface of the sample to be cleaned and gripping the particle attached on the surface of the sample with the gripping sections of the arms by closing the gripping sections; moving the arms of the nano tweezers gripping the particle onto the adhesion member such that the particle contacts the adhesion member; opening the gripping sections of the arms of the nano tweezers to release the particle from the nano tweezers while the particle is held on the adhesion member, and moving the nano tweezers away from the adhesion member to leave the particle on the adhesion member, thereby cleaning the surface of the sample.
