摘要： A lithography tool having a stage for supporting and positioning a substrate, an array configured to move the stage, and a cover plate positioned between the stage and the array. In various embodiments, the array may be either a magnet or coil array. The cover plate acts as a thermal insulator that helps even out temperature variations across the array. Consequently, thermal disturbances to the array or other parts of the lithography tool are reduced, resulting in a minimization of positioning errors. In addition, the cover plate also protects the array and provides a smooth surface in the event of a "crash" of the substrate stage.

摘要： A mover combination (226) for moving and positioning a device (34) includes a mover (328) that defines a fluid passageway (370) and a circulation system (330) having a passageway inlet (374) and a passageway outlet (376). The circulation system (330) directs a circulation fluid (378) into the fluid passageway (370). The circulation system (330) can include a liquid/gas separator (384) that is in fluid communication with the fluid passageway (370). With this design, the plumbing for the liquid (378A) and the gas (378B) can each be optimized. Additionally, the circulation system (330) can include a pressure control device (388) that controls the pressure of the circulation fluid (378) in at least a portion of the fluid passageway (370). With this design, the pressure control device (388) controls the pressure of the circulation fluid (378) near the fluid passageway (370) so that the temperature of the circulation fluid (378) at the passageway outlet (376) is approximately equal to the temperature of the circulation fluid (378) at the passageway inlet (374). Moreover, the circulation system (930) can include a pump assembly (980) that directs the circulation fluid (978) into the passageway inlet (974), and a pressure control device (996) that precisely controls a state of the circulation fluid (978) near the passageway inlet (974). With this design, the phase of the circulation fluid (978) at the passageway inlet (974) can be precisely controlled without restricting the flow of the circulation fluid (978).

摘要： Embodiments of the present invention are directed to a system and a method of controlling the flow and pressure of immersion fluid to provide stable conditions for immersion lithography. An immersion fluid is provided in a space (34) between a last optical element of an optical projection system and a workpiece during the immersion lithography process. For this purpose,a nozzle (20) is provided configured to supply immersion fluid in the gap between the last optical element and the workpiece, wherein the nozzle includes an inner cavity (34) to retain the immersion fluid in the gap and an outer cavity (53) to recover immersion fluid that exits the inner cavity.
