    摘要: The present invention relates to an illumination system including an illumination source, a beam conditioner placed in an optical path with the illumination source, a first diffractive array, a condenser system and a second diffractive array. The illumination source directs light through the beam conditioner onto the first diffractive array. The light is then directed to the condenser system placed in an optical path between the first diffractive array and second diffractive array. The condenser system includes a plurality of stationary optical elements and a plurality of movable optical elements. The plurality of movable optical elements are placed in an optical path with the plurality of stationary optical elements. The movable optical elements are capable of translation between the plurality of stationary optical element to zoom the light received from the first diffractive array. The second diffractive array is optically coupled to the condenser system, receives light from the condenser system, which in turn generates an illumination field at a reticle.

    摘要: An illumination method and system use a light source and illumination optics to illuminate a pattern generator. The illumination optics can include at least two devices. For example, if first and second diffractive and/or refractive devices are used, one can be a pupil defining element (PDE) and one can be a field defining element (FDE). In another example, a third diffractive or refractive element can be used to make light entering the illumination system uniform. When only two are used, the PDE forms one or more light beams having a defined profile. The FDE directs the one or more light beams having the defined profile, such that each directed beam substantially corresponds in size and shape to a desired illumination area(s) on the pattern generator. The directed beams are directed to impinge substantially only on the desired illumination area(s). Thus, using the PDE and the FDE increases optical efficiency of light impinging on the pattern generator and substantially reduces or eliminates stray light caused by light impinging on undesired areas of the pattern generator.

    摘要: A method and system allow for changing (continuously or variably) both a field height and pupil of a beam that illuminates an object field. In one example, the object field can have a pattern generator (e.g., one or more reticles, spatial light modulators, or the like) positioned therein. The system and method for changing both the field height and the pupil can include a field defining element, a pupil defining element, and first and second zoom systems. The field defining element (FDE) can generate a field height of an illumination beam. The first zoom system can allow for changing of the field height of the illumination beam. The pupil defining element (PDE) can generate a pupil of the illumination beam. The second zoom system can allow for changing of the pupil of the illumination beam.
