The invention provides a lithographic apparatus including an illumination system configured to condition a radiation beam, a patterning device support constructed to support a transmissive patterning device, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate, and a projection system configured to project the patterned radiation beam onto a target portion of the substrate, wherein the patterning device support is configured to hold a patterning device and wherein the lithographic apparatus includes a clamping device, the clamping device being configured to clamp the patterning device at the top side.

Lithographic apparatus and device manufacturing method for clamping a patterning device

A cooling apparatus is described that has a first cooling structure, in thermal contact with a heat source having a temperature greater than a cool structure, including a channel through which a cooling fluid is passed, an isolator between the heat source and the cool structure, the isolator in thermal contact with the first cooling structure and including a material of low thermal conductivity, and a second cooling structure between the isolator and the cool structure, the second cooling structure including a channel through which cooling fluid is passed.

Apparatus for cooling

A lithographic apparatus includes a support constructed to support a patterning device. The patterning device is capable of imparting a radiation beam with a pattern in its cross-section to form a patterned radiation beam. The support includes a force actuator device to exert a force onto the patterning device in a direction of movement of the support. The force actuator device includes a movable part which is pivotably about a pivot axis and thereby connected to the support. The movable part is in the direction of movement of the support substantially balanced with respect to the pivot axis. The force actuator device further includes an actuator to exert via the movable part the force onto the patterning device, to at least partly compensate for the information or a risk of slippage due to acceleration of the support in the direction of movement.

Lithographic apparatus and stage apparatus

A motor includes a magnet assembly to generate a magnetic field. The field includes along the first direction parts which are alternately orientated in the first and the second direction. The parts extend in a third direction which is perpendicular to the first and the second direction. The motor further includes a first coil winding to carry a first current. The first coil winding to extend in the first direction between parts of the magnetic field orientated in the second direction, to generate the force in the first direction. The motor also includes a second coil winding to carry a second current. The second coil winding to extend in the first direction between parts of the magnetic field substantially orientated in the first direction, to generate the force in the second direction.

Lithographic apparatus and motor

The mask in a lithographic apparatus is clamped on a first side using a first clamping device and on a second side, different from the first side, using a second clamping device. The clamping forces are preferably applied using thin membranes. The first clamp clamps the substrate in directions parallel to the plane of the patterning device, perpendicular to the plane of the patterning device and rotationally. The second clamping device clamps the patterning device only in directions parallel to the plane of the substrate.

Lithographic apparatus and device manufacturing method

A moveable member is provided which extends the top surface of a substrate table, in plan, beyond a bumper which protects the substrate table during collision. The moveable member may be retracted to a retracted position in which it no longer extends beyond the bumper. In this way it is possible to move two substrate tables together and to allow the retractable member to pass under a liquid supply system which normally provides liquid between the projection system and a substrate without turning off of the liquid supply system.
