    摘要: A stage assembly and support system are provided to stabilize a stage base, such as a wafer stage base or a reticle stage base, minimizing forces transmitted from the stage assembly to a stationary surface, such as the ground, and thereby preventing vibration of other parts or systems in a wafer manufacturing process. Depending of the applicable photolithography system, a reticle stage and/or a wafer stage are accelerated in response to a wafer manufacturing control system to position the semiconductor substrates. The jerking motions of the reticle stage and/or wafer stage cause reaction forces acting on the reticle stage base and/or wafer stage base. The reaction forces induce vibration to the stationary surface and surrounding parts of the photolithography system. The wafer stage assembly and support system according to this invention allow the reticle stage base and/or wafer stage base to move relative the stationary surface. The base, acting as a massive reaction mass, stores a kinetic energy from the reaction force and gradually dissipates such energy by applying small forces to the reaction mass. The stage assembly and support system according to this invention are also capable of canceling any disturbance forces acting on the base.

    摘要: A stage assembly (220) that moves a work piece (200) about a first axis and along a first axis includes a first stage (238), a second stage (240) that retains the work piece (200), a second mover assembly (244), a measurement system, and an initialization system (1081A). The second mover assembly (244) moves the second stage (240) relative to the first stage (238) about the first axis. The measurement system (22) monitors the position of the second stage (240) about the first axis when the second stage (240) is positioned within a working range about the first axis. The initialization system (1081A) facilitates movement of the second stage (240) about the first axis when the second stage (240) is rotated about the first axis outside the working range. The second mover assembly (244) can include a mover (255) and a dampener (410) that reduces the transmission of vibration from the first stage (238) to the second stage (240). In addition, the stage assembly (220) can include a control system (24) that directs power to the mover (255) to position the second stage (240) and to compensate for vibration of the first stage (238).

    摘要: An active vibration isolation system includes a pneumatic control system and an electronic control system. The pneumatic control system supports a mass sensitive to vibration and isolates the mass from high frequency external disturbances. The electronic control system isolates the mass from low frequency external disturbances. The pneumatic control system includes a compliance chamber filled with a fluid to pneumatically support the mass, apparatus for directly measuring a pressure level in the compliance chamber, and apparatus for controlling the pressure level to minimize the effects of pressure variation in the compliance chamber. The measuring apparatus includes an instrument to measure an absolute pressure level of the compliance chamber or an instrument to measure a differential pressure level between the compliance chamber and a reference chamber having a predetermined pressure level.

    摘要: A wafer stage countermass assembly generally includes a base supporting one or more stages and first and second countermasses. The first and second stages move in one or more degrees of freedom. The countermasses move in at least one degree of freedom and, under ideal conditions, move to counter the movement of the stages in operation and thus preserve the systems center of gravity to avoid unwanted body motion. However, under actual conditions the countermasses may under travel or over travel their ideal trajectory. To more closely track the ideal trajectory, a controller actuates trim motors to apply small forces to the countermasses to push them towards a reference position in the Y direction. A second embodiment also takes into account the X position the stage(s) to cancel torque.

    摘要: Methods, apparatus, and systems are disclosed for identifying force-ripple and/or side-forces in actuators used for moving a multiple-axis stage. The identified force-ripple and/or side-forces can be mapped, and maps of corresponding position-dependent compensation ratios useful for correcting same are obtained. The methods are especially useful for stages providing motion in at least one degree of freedom using multiple (redundant) actuators. In an exemplary method a stage member is displaced, using at least one selected actuator, multiple times over a set distance in the range of motion of the subject actuator(s). Each displacement has a predetermined trajectory and respective starting point in the range. For each displacement, respective section force-command(s) are extracted and normalized to a reference section force-command to define a section compensation-ratio. Multiple section compensation-ratios are assembled, as functions of displacement in the range, to provide a map of compensation ratios for the actuator(s) throughout the range.
