| 20110090475 | SCANNING EXPOSURE APPARATUS, CONTROL APPARATUS AND METHOD OF MANUFACTURING DEVICE - A scanning exposure apparatus includes a first feedback loop including a first controlled object including an original stage and controlling a position of the original stage, a second feedback loop including a second controlled object including a substrate stage and controlling a position of the substrate stage, and a feedback unit including a first calculator and feed backing a synchronization error between the original stage and the substrate stage to the first feedback loop and the second feedback loop via the first calculator, wherein a transfer function from a first target value for the first controlled object to a first controlled value of the first controlled object and that from a second target value for the second controlled object to a second controlled value of the second controlled object are equal, and the exposure is performed at least during a period in which the original and the substrate are accelerated. | 04-21-2011 |
