    • A lithographic apparatus comprises an illumination system for supplying a beam of radiation, a patterning arrangement incorporating an array of individually controllable elements for imparting a pattern to the beam cross-section, a substrate table for supporting a substrate, and a projection system incorporating a microlens array for projecting the beam onto a target portion of the substrate. An error compensator is provided for supplying error correction values for compensating for the effect of positional errors in the microlens array, and a grey scale modulator is provided for supplying drive signals to controllable elements of the patterning arrangement in dependence on the error correction values in order to compensate for the effect of positional errors in the microlens array by varying the intensity of some parts of the pattern relative to other parts of the pattern.

    • A lithographic apparatus patterns a projection beam of radiation using a patterning system. A substrate is supported on a substrate table and the patterned beam is projected onto the substrate on the table. A substrate displacement control system displaces the substrate relative to the table and the projection system in a predetermined direction, such that the patterned beam is scanned across the substrate. The position of the substrate relative to the table and the patterned beam is determined by the displacement control system. The displacement control system comprises at least one component that is displaceable with the substrate and a positioning apparatus to place that component in contact with the substrate, such that the component is displaced with the substrate as the projection beam is scanned across the substrate and such that the component is lifted from the substrate after the projection beams has been scanned across the substrate. The component could be, for example, an elongate strip carrying alignment marks or a magnet which is used to apply a displacement force to the substrate.
    • 光刻设备使用图案化系统对辐射投影束进行图案化。 衬底被支撑在衬底台上,并且将图案化的光束投影到桌子上的衬底上。 基板位移控制系统使基板相对于工作台和投影系统沿预定方向移位,使得图案化的光束跨过基板扫描。 基板相对于工作台和图案化梁的位置由位移控制系统确定。 位移控制系统包括至少一个可与衬底移位的部件和定位装置以使该部件与衬底接触,使得当投影束跨过衬底扫描时,该部件与衬底一起移位,并且使得 在投影光束被扫描穿过基板之后,该部件被从基板提升。 组件可以是例如带有对准标记的细长带或用于向基板施加位移力的磁体。
