    摘要: A method includes directing a beam of radiation along an optical axis toward a workpiece support, measuring a spectrum of the beam at a first time to obtain a first profile, measuring the spectrum of the beam at a second time to obtain a second profile, determining a spectral difference between the two profiles, and adjusting a position of the workpiece support along the optical axis based on the difference. A different aspect involves an apparatus having a workpiece support, beam directing structure that directs a beam of radiation along an optical axis toward the workpiece support, spectrum measuring structure that measures a spectrum of the beam at first and second times to obtain respective first and second profiles, processing structure that determines a difference between the two profiles, and support adjusting structure that adjusts a position of the workpiece support along the optical axis based on the difference.

    摘要: A method for transferring a pattern from a mask to a substrate (or wafer), comprises dividing a mask generation data file into a plurality of segments. The segments include a main pattern area and a stitching area. Each stitching area contains a respective common pattern. An image of an illuminated portion of the main pattern area is formed. Connection ends of the segments in a substrate area (or wafer area) are illuminated with an illumination beam. An image of the illuminated portion of the main pattern area is formed, and a halftone gray level dosage distribution is produced in the substrate area (or wafer area) corresponding to the common pattern. The common patterns of adjacent segments substantially overlap in the substrate area (or wafer area).
