Abstract: Disclosed is an object table for holding an object, comprising: an electrostatic clamp arranged to clamp the object on the object table; a neutralizer arranged to neutralize a residual charge of the electrostatic clamp; a control unit arranged to control the neutralizer, wherein the residual charge is an electrostatic charge present on the electrostatic clamp when no voltage is applied to the electrostatic clamp.

Abstract: An apparatus for use in a metrology process or a lithographic process, the apparatus including: an object support module adapted to hold an object; and a first gas shower arranged on a first side of the object support module and adapted to emit a gas with a first velocity in a first gas direction which is a horizontal direction to cause a net gas flow in the apparatus to be a substantially horizontal gas flow in the first gas direction at least above the object support module.

Abstract: An encoder includes an optical component and an enclosing device having a first surface portion and a second surface portion. The first surface portion is arranged to receive from an ambient environment a first radiation beam. The second surface portion is arranged to receive from the ambient environment a second radiation beam. The optical component is arranged to combine the first and second radiation beams. The enclosing device is arranged to propagate the first radiation beam along a first path. The first path is between the first surface portion and the optical component. The enclosing device is arranged to propagate the second radiation beam along a second path. The second path is between the second surface portion and the optical component. The enclosing device is arranged to enclose a space, so as to isolate the first path and the second path from the ambient environment.

Abstract: A sensor for use in lithographic apparatus of an immersion type and which, in use, comes into contact with the immersion liquid is arranged so that the thermal resistance of a first heat path from a transducer of the sensor to a temperature conditioning device is less than the thermal resistance of a second heat flow path from the transducer to the immersion liquid. Thus, heat flow is preferentially towards the temperature conditioning device and not the immersion liquid so that temperature-induced disturbance in the immersion liquid is reduced or minimized.

Abstract: A stage apparatus for a particle-beam apparatus is disclosed. A particle beam apparatus may comprise a conductive object and an object table, the object table being configured to support an object. The object table comprises a table body and a conductive coating, the conductive coating being provided on at least a portion of a surface of the table body. The conductive object is disposed proximate to the conductive coating and the table body is provided with a feature proximate to an edge portion of the conductive coating. Said feature is arranged so as to reduce an electric field strength in the vicinity of the edge portion of the conductive coating when a voltage is applied to both the conductive object and the conductive coating.
