    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.

    Abstract: Systems and methods for wafer grounding and wafer grounding location adjustment are disclosed. A first method may include receiving a first value of an electric characteristic associated with the wafer being grounded by an electric signal; determining a first control parameter using at least the first value; and controlling a characteristic of the electric signal using the first control parameter and the first value. A second method for adjusting a grounding location for a wafer may include terminating an electric connection between the wafer and at least one grounding pin in contact the wafer; adjusting a relative position between the wafer and the grounding pin; and restoring the electric connection between the grounding pin and the wafer. A third method may include causing a grounding pin to penetrate through a coating on the wafer by impact; and establishing an electrical connection between the grounding pin and the wafer.

    Abstract: A feedthrough for providing an electrical connection is provided. The feedthrough comprises a conductor and a quartz or a glass structure configured to surround at least a portion of the conductor and provide isolation to the conductor. The conductor and the quartz or glass structure may be coaxially arranged. The feedthrough can provide an electrical connection between an inside and outside of a vacuum chamber that contains a sample.

    Abstract: A support such as a clamp (310) is configured to releasably hold a patterning device such as a reticle (300) to secure it and prevent heat-induced deformation of it. For example, an electrostatic clamp includes a first substrate (312) having opposing first (313) and second (315) surfaces, a plurality of burls (316) located on the first surface and configured to contact the reticle, a second substrate (314) having opposing first (317) and second (319) surfaces. The first surface of the second substrate is coupled to the second surface of the first substrate. A plurality of cooling elements (318) are located between the first surface of the second substrate and the second surface of the first substrate. The cooling elements are configured to cause electrons to travel from the second surface of the first substrate to the first surface of the second substrate. Each cooling element is substantially aligned with a respective burl.
