    • A system and method use a lithographic apparatus to direct a plurality of patterned beams onto a substrate supported on a substrate table. The patterned beams are projected onto target portions of the substrate and relative displacement between the substrate and the patterned beams causes the beams to be scanned across the substrate. A first projection device projects a first relatively large area patterned beam which extends across a substantial proportion of the substrate. At least one second relatively small area patterned beam is selectively positioned relative to the first projection device at least in a direction transverse to the predetermined direction. The second beam may be used to expose an elongate portion of the substrate which extends in the direction of relative displacement. At least one third patterned beam of relatively small area may be provided which is selectively displaceable relative to the substrate table during relative displacement between the substrate and the first beam. The third patterned beam may be used to expose an elongate portion of the substrate which extends transversely to the direction of relative displacement.
    • 系统和方法使用光刻设备将多个图案化的光束引导到支撑在衬底台上的衬底上。 图案化的光束投影到基板的目标部分上,并且基板和图案化的光束之间的相对位移使得光束跨越基板被扫描。 第一投影装置投射第一相对较大面积的图案化的束,其延伸穿过基本上相当大比例的衬底。 至少一个第二相对小的区域图案化的光束至少在横向于预定方向的方向上相对于第一投影装置选择性地定位。 可以使用第二梁来暴露沿相对位移方向延伸的衬底的细长部分。 可以提供相对小面积的至少三分之一图案化的光束,其在衬底和第一光束之间的相对位移期间可相对于衬底台选择性地移位。 第三图案化束可以用于暴露横向于相对位移方向延伸的衬底的细长部分。
