    摘要： A vibration-assisted positioning stage comprising a stage, a roller bearing, an compliant joint interconnecting the roller bearing to the stage such that the compliant joint is sufficiently compliant in a direction of movement to permit reliable alignment of the stage and further permit dithering, and a dithering force actuator applying a dithering force directly to the roller bearing to permit the dithering of the stage. The dithering forces can be applied out of phase to minimize vibration of the stage. Furthermore, the controller of the stage can be employed to suppress any remnant vibrations of the stage due to dithering. A supervisory control system can intelligently adapt the parameters of the dithering signal to optimize the performance of the stage as friction changes.

    摘要： An exemplary stage assembly has movable stage mass and counter-mass. A stage motor is coupled to the stage mass and counter-mass such that stage-mass motion imparted by the stage motor causes a reactive motion of the counter-mass counter to the motion of the stage mass. At least one trim-motor is coupled to the counter-mass. A control system commands the trim-motor to regulate movement of the counter-mass in reaction to stage-mass motion. A PI feedback controller receives the following-error of the counter-mass and generates corresponding center-of-gravity (CG) force commands and trim-motor force commands to the trim-motor(s) to produce corrective counter-mass motion. A trim-motor force limiter receives trim-motor force commands and produces corresponding limited trim-motor force commands that are fed back as actual CG force commands to the feedback controller to modify integral terms of the feedback controller according to the limited trim-motor force commands.

    摘要： An imprint lithography apparatus and manufacturing method can lead to mechanical stress being formed in a substrate to which an imprint pattern is being applied. This may cause strain within the substrate leading to misalignment of a subsequent pattern with an earlier pattern in a part of the substrate, which is strained. An apparatus and method is disclosed which allows for stress relaxation in the substrate prior to further patterning to reduce, minimize or prevent such misalignment from residual strain. This is achieved by locally unclamping a portion of substrate (including optionally the entire substrate) from a corresponding portion of substrate holder so that mechanical stress leading to local strain may relax prior to further patterning. To overcome residual frictional force between the substrate and substrate holder, the substrate and substrate holder may be physically separated prior to further patterning.
