    摘要: A method for the high-precision measurement of coordinates of at least one structure on a substrate. A stage traversable in X/Y coordinate directions is provided, which is placed in an interferometric-optical measuring system. The structure on the substrate is imaged on at least one detector (34) via a measuring objective (21) having its optical axis (20) aligned in the Z coordinate direction. The structure is imaged with the so-called Dual Scan. Systematic errors can thereby be eliminated.

    摘要: The invention is based on a method and an apparatus for scanning a semiconductor wafer (1), on-the-fly images of regions on the wafer being acquired using a camera (3). Upon a scan line changeover, a continuously curved displacement track is generated by at least partial superimposition of the relative motions between the wafer (1) and camera (3) in the direction of the scan lines and perpendicular thereto. As a result, time is saved and wafer throughput is increased.

    摘要: A measuring apparatus for determining relative positions of a positioning stage arranged in a moveable fashion in at least one direction by a predeterminable maximum traversing path. The measuring device comprises at least one interferometric measuring means and at least one interferometric correction means. An interferometric measuring means is operable with the laser light of a laser of at least one wavelength. Correction results can be generated with the interferometric correction means allowing conclusions to be drawn with respect to the actual wavelength of the laser light during a position determination of the positioning stage in order to take into account variations of the wavelength of the laser light, in particular due to ambient conditions, when evaluating the measuring results. The interferometric correction means is arranged proximate to the interferometric measuring means, and the proximity corresponds to a predeterminable portion of the maximum traversing path of the positioning stage.
