    摘要: 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.

    摘要: A target (16) for a metrology system (10) that monitors the position of an object (12) includes a target housing (225) and a photo detector assembly (226). The target housing (225) can include a first target surface (218A), and a second target surface (218B) that is at an angle relative to the first target surface (218A). The photo detector assembly (226) can include a first detector (220A) that is secured to the first target surface (218A), and a second detector (220B) that is secured to the second target surface (218B). Each of the detectors (220A) (220B) can be a quad cell that includes four detector cells (238A) (238B) (238C) (238D) that are separated by a gap (236).
