    Abstract: A support apparatus for a lithographic apparatus has an object holder and an extraction body radially outward of the object holder. The object holder is configured to support an object. The extraction body includes an extraction opening configured to extract fluid from a top surface of the support apparatus. The extraction body is spaced from the object holder such that the extraction body is substantially decoupled from the object holder. The extraction body includes a projection configured such that it surrounds the object holder and such that, in use, a layer of immersion liquid is retained on the projection and in contact with an object supported on the object holder.

    Abstract: A suction clamp for clamping an object. The suction clamp includes a base structure including a base and a connection area, and a first pad for receiving the object. The suction clamp further includes a resilient member connecting the first pad to the connection area of the base structure such that the first pad is moveable relative to the base between a receiving position for receiving the object and a clamping position for clamping the object, wherein the resilient member is adapted to bias the first pad to the receiving position. The suction clamp further includes a suction opening arranged in the base and adapted to be connected to a suction device for providing a suction force for clamping the object on the first pad.

    Abstract: The invention provides a stage apparatus, comprising an object support comprising a ring shaped protrusion having an outer radius in a first plane, and configured to support an object with a radius in the first plane larger than the outer radius of the ring shaped protrusion. The stage apparatus further comprises a sensor module configured to detect the object support, and the object when it is arranged on the object support. The stage apparatus further comprises a processing unit configured to receive one or more signals from the sensor module, and to determine, based on said one or more signals, a position of the object relative to the ring shaped protrusion when the object is arranged on the object support. The processing unit is further configured to determine, based on said position of the object, an offset value representing the position of the object relative to the ring shaped protrusion.

    Abstract: The invention provides a stage apparatus comprising an object support, a plurality of support members, a gripper and a control unit. The object support comprises a surface for mounting an object on, the surface extending in a plane. The plurality of support members are for supporting the object, and are arranged to receive the object from a gripper and to arrange the object on the surface and/or vice versa. The support members are moveable in at least a first direction which is perpendicular to the plane. The control unit is arranged to receive shape information regarding an out-of-plane-shape of the object, and is arranged to control positions of the support members. The control unit is arranged to tilt the object while supported by the support members by controlling the positions so as to reduce a space consumption of the object in the first direction, based on the shape information.
