Abstract:
1. A cleaning apparatus comprising: an adhesive sheet including a base material and an adhesive surface for removing particles, the adhesive surface being configured to adhere to a portion to be cleaned of a vacuum processing apparatus; a conductive sheet in contact with the base material; a pressing member configured to press the conductive sheet; a voltage applying mechanism configured to apply positive or negative voltage to the conductive sheet; and a pressing force controlling mechanism configured to control a force that adheres the adhesive sheet to a portion to be cleaned of a vacuum processing apparatus via the pressing member; wherein the pressing member has a shape similar to a surface shape of the portion to be cleaned of the vacuum processing apparatus; and wherein the adhesive surface generates an electrostatic attraction by positive or negative voltage applied to the conductive sheet by the voltage applying mechanism.
