    摘要: A stage assembly (10) for moving and positioning a device (30) includes a stage (14), a stage mover assembly (16), a device table (18), a table mover assembly (20) and a damping assembly (22). The table mover assembly (20) moves the device table (18) along a Z axis, about an X axis and about a Y axis relative to the stage (14) and generates reaction forces. The damping assembly (22) is coupled to the table mover assembly (20). Uniquely, the damping assembly (22) reduces the reaction forces created by the table mover assembly (20) that are transferred to the stage (14).

    摘要: A high accuracy stage supported in six degrees of freedom by electromagnetic bearings. Movements in the horizontal plane of the stage are controlled by variable reluctance actuators which are mounted between the high accuracy stage and a coarse stage so as not to distort the high accuracy stage during movements thereof. The high accuracy stage is supported in three vertical degrees of freedom by electromagnetic actuators disposed between the coarse stage and the high accuracy stage and aided by a supplemental vertical support disposed adjacent to the actuators. Preferably, the high accuracy stage is suspended from a bar supported by the supplemental vertical support, which is preferably air bellows.

    摘要: A stage assembly (10) for moving and positioning a device (26) includes a device table (20), a device holder (24) that retains the device (26), and a stage mover assembly (14). The stage assembly (10) includes one or more features that can isolate the device holder 24 and the device (26) from deformation. In some embodiments, the stage assembly (10) allows precise rotation of the device (26) between a first position (42) and a second position (44) without influencing the flatness of the device (26) and without deflecting and distorting the device (26). For example, the stage assembly (10) can include a carrier (60) and a holder connector assembly (62). The carrier (60) is supported above the device table (20) and rotates relative to the device table (20). The holder connector assembly (62) connects the device holder (24) to the carrier (60). Further, the stage assembly (10) can include a holder mover (120) that rotates the device holder (24) relative to the device table (20). Additionally, the stage assembly (10) can include a fluid connector (94) that connects the device holder (24) in fluid communication with the device table (20).

    摘要: Adaptive optical elements for use in high precision lithography exposure are provided with an array of discrete actuators to provide highly stable and repeatable correction of the shape of an optical element to an accuracy of a small fraction of a very short wavelength of light in the EUV range of 1 to 50 nanometers, responsive to a metrology source and sensor arrangement. The actuators are matched to the deformation characteristics of the adaptive optical elements. Preferably, the actuators provide both positive and negative force for outward and/or inward deflection continuously over the surface of the mirror. The surface of the optical element may thus be accurately, controllably and repeatably deformed to within an allowable deformation limit to optimize optical performance of an optical system for high precision lithography exposure.

    摘要: A positioning method in which a system performs operations relative to areas on a substrate by a series of relative movements between the system and substrate scanning exposures. The method includes the steps of disposing a first area relative to a system performing an operation relative to the first area, and moving the substrate from a first position where the first operation relative to the first area has finished to a second position where a second operation relative to a second area is to start, and synchronously moving the system from a third position where the first operation relative to the first area has finished to a fourth position where the second operation relative to the second area is to start. An acceleration of the substrate during movement from the first position to the second position and an acceleration of the system during movement from the third position to the fourth position continually have absolute values greater than zero.
