    摘要: Process tools and methods are disclosed that involve interferometric and other measurements of movements and positions relative to a process position, such as movements and positions of a stage relative to a lithographic optical system. An exemplary apparatus includes a stage that places a workpiece relative to the tool, and that is movable in at least one direction relative to the tool. At least one first interferometer system is situated relative to the stage to determine stage position in a movement direction relative to the process position. A movement-measuring device determines displacement of the tool from the process position. Using data from the interferometer system and movement-measuring device a processor determines a position of the stage relative to the tool. The processor also corrects the determined position for displacement of the tool.

    摘要: A method and apparatus for measuring the coordinate position of a stage on which a semiconductor wafer or the like is placed. Two .theta. interferometers are provided as measuring means for detecting local curving deviations of reflecting surfaces of two plane mirrors perpendicular to each other which mirrors are provided on the stage for detection of the coordinate position of the stage based on the use of light wave interferometers. The curving deviations of the reflecting surfaces of the plane mirrors are measured with the .theta. interferometers to calculate the difference thereby measured and, hence, the true curving deviations of the reflecting surfaces while cancelling out errors in linear movement of the stage. The position of the stage measured with the coordinate position measuring light wave interferometers is corrected by values corresponding to the true curving deviations.
