Abstract:
1. A micro-machining dust removing method of removing the micro-machining dust generated at the time of machining by electrophoresis while a workpiece is machined within a liquid using a probe tip, the method comprising the steps of: dipping at least the probe tip and a first and second electrodes in liquid with a probe having the probe tip provided on or above the workpiece, and the probe tip sandwiched between the first electrode and the second electrodes; specifying a position where the machining is to be performed by observing the workpiece by AFM observation utilizing the probe and locating the probe tip on the specified position of the workpiece; applying a predetermined voltage to between the first electrode and the second electrode; and machining the workpiece using the probe tip by moving the probe tip relative to the workpiece.
