Embodiments of the invention provide improved thermal conductivity within, among other things, electromagnetic coils, coil assemblies, electric motors, and lithography devices. In one embodiment, a thermally conductive coil includes at least two adjacent coil layers. The coil layers include windings of wires formed from a conductor and an insulator that electrically insulates the windings within each coil layer. In some cases the insulator of the wires is at least partially absent along an outer surface of one or both coil layers to increase the thermal conductivity between the coil layers. In some embodiments, an insulation layer is provided between the coil layers to electrically insulate the coil layers. In some cases the insulation layer has a thermal conductivity greater than the thermal conductivity of the wire insulator.

According to one aspect of the present invention, a motor arrangement includes at least one coil, a cover plate, and a shield layer. The at least one coil has a first side and a second side. The cover plate is positioned substantially over the first side of the at least one coil at a distance from the at least one coil. The shield layer is positioned between the first side of the at least one coil and the cover plate, and has a top surface. The top surface contacts the cover plate, and includes a liquid and a gas that form a mixture and cause the top surface to have a substantially constant temperature.

A vibration isolator (200) for isolating a first assembly (202) from vibration from a second assembly (204) includes a housing (206) that is secured to the second assembly (204) and a pendulum assembly (208). The pendulum assembly (208) includes one or more pistons (226) and a connector assembly (224). The piston (226) is coupled to the first assembly (202). The connector assembly (224) couples the piston (226) to the housing (206) and allows the piston (226) to swing laterally relative to the housing (206). The vibration isolator (200) can also include a pendulum support (264) and/or a mover (580) that moves the piston (226) and assists in supporting the load of the first assembly (202).

According to one aspect of the present invention, an apparatus includes a surface and a first array. The surface emits radiation, and the first array is arranged over the surface and arranged to provide cooling to the surface, the first array including a plurality of TECs. At least a first sensing arrangement is substantially integrated with the first array, wherein the first sensing arrangement is arranged to make a non-contact measurement associated with the surface. The apparatus also includes a controller arranged to obtain the non-contact measurement and to use the non-contact measurement to control the cooling provided by the first array.

An apparatus for controlling the distortion of a reticle (28) includes a temperature adjuster (258) and a control system (226). The temperature adjuster (258) includes a plurality of adjuster elements (258E) that individually adjust the temperature of a plurality of regions (28R) of the reticle (28). The control system (226) includes a state observer (250) and a controller (260). The state observer (250) estimates an estimated physical condition (250C) of the reticle (28). The controller (260) controls the adjuster elements (258E) of the temperature adjuster (258) based at least in part on the estimated physical condition (250C).

A device container assembly (30) for storing a reticle (26) includes a device container (246) and a shield assembly (250). The device container (246) encircles the reticle (26). Further, the device container (246) includes a fluid port (254) that allows for the flow of fluid (276) into and out of the device container (246). The shield assembly (250) is encircled by the device container (246). Further, the shield assembly (250) is positioned between the fluid port (254) and the reticle (26) when the reticle (26) is positioned within the device container (246). The shield assembly (250) can inhibit contaminants (278) near the fluid port (254) from being deposited on the reticle (26) and can maintain the integrity of the reticle (26).
