    摘要: In a lithographic process for fabrication of integrated circuit chips, a projection exposure machine is used to print a mask pattern onto each of a plurality of shot areas defined on a substrate, where an alignment method for establishing alignment between each shot area on the substrate and the mask pattern is performed. The alignment method comprises the step of forming on the substrate a regular pattern which comprises a plurality of pattern elements regularly distributed over the plurality of shot areas, and the step of performing an alignment operation based on the position of the regular pattern so as to establish alignment between each of the plurality of shot areas and the mask pattern. An exposure apparatus may be used to form the regular pattern on the substrate. The exposure apparatus comprises a light source for emitting a primary light beam, a beam-splitting optical system for splitting the primary light beam into a plurality of secondary light beams which are coherent with each other, and an objective optical system for modifying each secondary light beam into a substantially plane wave light beam, and for illuminating a region of a photoresist-coated substrate with the secondary light beams at different incident angles, the region of the substrate extending over a plurality of shot areas defined on the substrate, wherein the region is exposed to a regular pattern of light of interference fringes produced on the substrate from the plurality of secondary light beams.

    摘要: A laser working system comprises supplying means for supplying a laser beam, a working unit which includes a stage for supporting a workpiece and means for exposing the workpiece to the laser beam, and a room unit which includes wall means for surrounding the working unit and accomodates the working unit to spatially isolate it from outside of the wall means. The supplying means is arranged outside the room unit and includes first and second laser units each for generating the laser beam.The laser working system further comprises beam guiding means which creates first light path for optically communicating the first laser unit with the working unit through the wall means, and second light path for optically communicating the second laser unit with the working unit through the wall means, respectively.
