Beschreibung
Zusammenfassung:	Methods and systems are described for reducing particles in the vicinity of an electrostatic chuck (300) in which a cleaning reticle or substrate (320) is secured to the chuck, the cleaning reticle or substrate having surfaces partially devoid of conductive material so that an electric field from the chuck can pass through to a volume adjacent the substrate to draw particles (360) in the volume to the surface of the substrate. Voltage supplied to the chuck may have an alternating polarity to enhance the attraction of particles to the surface.
