    摘要: A stage assembly (10) for moving and positioning a device (26) is provided herein. The stage assembly (10) includes a stage base (12), a device table (48), a stage mover assembly (16), a measurement system (20), and a control system (22). The stage mover assembly (16) moves the device table (48) along an X axis, along a Y axis, and about a Z axis relative to the stage base (12). The measurement system (20) includes a first X mirror (25A) for monitoring the position of the device table (48) in an alignment position (31A) and a second X mirror (25B) for monitoring the position of the device table (48) in an operational position (31B). In one embodiment, the stage assembly (10) includes a first fiducial mark (76) and a second fiducial mark (78) that are secured to the device table (48) to determine the relative position of the X mirrors (25A)(25B). Alternately, in another embodiment, the stage assembly additionally includes a third fiducial mark (80) secured to the device table (48) for determining the relative positions of the X mirrors (25A)(25B). In both embodiments, the control system (22) utilizes the measured position of the fiducial marks relative to the first X mirror (25A) and the second X mirror (25B) to determine the position of the first X mirror (25A) relative to the second X mirror (25B). These features allow for more accurate positioning of the device (26) by the stage assembly (10) and better performance of the stage assembly (10).

    摘要: After exposure of a divided area on a wafer is completed, for exposure of the next divided area, a control unit sends configuration information on control parameters necessary to expose the next divided area to a stage control system, sometime before the stage control system begins deceleration of a reticle stage and a wafer stage in a scanning direction. Therefore, both stages do not have to be suspended before acceleration for the stage control system to receive the configuration information on control parameters necessary to expose the next divided area, and since suspension time is not required, throughput can be improved. In this case, no serious problems occur, so the performance of other devices is not disturbed.

    摘要: A table holding a substrate thereon is placed on a focusing and levelling stage through three fulcrums, and a calculator receives as inputs the coordinates values of the table measured by an interferometer, the amount of positional deviation between the surface of a wafer and a predetermined fiducial plane at each of a plurality of measuring points on the substrate which is measured by a multipoint AF sensor, and a weight coefficient given to be to the amount of positional deviation at each of the plurality of measuring points, thereby calculating the residual deviation at each of the three fulcrums. A controller adopts the PID control system and controls the amounts of displacement of the three fulcrums on the basis of the residual deviation calculated by the calculator, the integrated value of this residual deviation and the differentiated value of this residual deviation.

    摘要: An exposure apparatus is designed to reduce the influences of alignment errors due to dynamic fluctuations and improve the throughput while basically using an off-axis alignment scheme. A wafer stage on which a test wafer is place is step-driven in accordance with a shot arrangement in an exposure operation. Subsequently, variations in position of the wafer stage, which occur while the position of alignment marks observed by a TTR alignment system coincide with aimed positions, are stored. In an exposure operation with respect to a wafer to be exposed, the prestored variations in position of the wafer stage are reproduced when alignment of each shot area is performed in accordance with the position of each alignment mark, detected by an off-axis alignment system.
