摘要： The present invention provides an illumination system for varying the size of an illumination field incident to a scattering optical element. The illumination field is subsequently imaged to a reticle in a photolithographic process. The illumination system includes, in series along an optical axis of the illumination system, an optical source, a beam conditioner, a first optical integrator, a first or input collimating lens, a zoom array integrator (ZAI), a second or output collimating lens, the optical scattering element, a relay lens, and the reticle. The ZAI includes an assembly of fixed and moveable lens components arranged to vary the size of the illumination field throughout a zoom range of the ZAI while maintaining telecentric illumination at a substantially fixed numerical aperture. Illumination telecentricity and substantially fixed numerical apertures are maintained at both the scattering optical element and the reticle throughout the zoom range.

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.
