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： A mover (344) that moves a stage (238) along a first axis and along a second axis includes a magnetic component (354), a conductor component (356), and a control system (324). The magnetic component (354) includes one or more magnets (354D) that are surrounded by a magnetic field. The conductor component (356) is positioned near the magnetic component (354). Further, the conductor component (356) interacts with the magnetic component (354) when current is directed to the conductor component (356). The control system (224) directs current to the conductor component (356) to generate a controllable force along the first axis and a controllable force along the second axis. With this design, the same mover (344) can be used to move the stage (238) along two degrees of freedom (“DOF”). Further, the conductor component (356) including a first phase coil (364A) and a second phase coil (364B) that partly overlaps the first phase coil (364A). With this design, the size and efficiency of the mover (334) is significantly improved. As a result thereof, the overall footprint of the mover (344) can be reduced and the heat generated by the mover (344) is minimized.

摘要： A coolant cools an object (such as, for example, a coil of a linear motor that drives a stage of an exposure apparatus) while suppressing the generation of a temperature distribution in various parts of the object being cooled by using a coolant that includes a first component and a second component dispersed in the first component, the second component increases in temperature by a lesser amount than the first component when a predetermined amount of heat is absorbed by the first and second components, respectively. The second component may be a substance that changes phase (for example, from a solid to a liquid or from a liquid to a gas) in order to absorb the predetermined amount of heat. The second component may have a higher heat capacity than the first component, and may not change phase when it absorbs heat to cool the object.
