摘要： A magnification loupe carried by spectacles has a Galilean lens system comprising a single-element eyepiece lens and a two-element objective lens. The loupes may be mounted to eyeglass frames by a flip-up mounting member, or they may be mounted through the eyeglass lenses of the spectacles. The loupes provide high magnification while minimizing weight to thereby reduce strain and discomfort to users. In an exemplary embodiment, the objective lens has a non-circular shape that provides a wide field of view while further minimizing the weight of the loupe. A correction lens may be interchangeably coupled to the loupe housing to permit selective replacement with another correction lens to vary the working distance of the loupe.

摘要： An optical system includes multiple cubic crystalline optical elements aligned along a common optical axis and having their crystal lattices oriented with respect to each other to minimize the effects of intrinsic birefringence and produce a system with reduced retardance. The optical system may be a refractive or catadioptric system having a high numerical aperture and using light with a wavelength at or below 248 nanometers. The net retardance of the system is less than the sum of the retardance contributions of the respective optical elements as the elements are oriented such that the intrinsic birefringences of the individual elements cancel each other out. In one embodiment, two [110] cubic crystalline optical elements are clocked with respect to one another and used in conjunction with a [100] cubic crystalline optical element to reduce retardance. Various birefringent elements, wave plates, and combinations thereof provide additional correction for residual retardance and wavefront aberrations. The optical system may be used in a photolithography tool to pattern substrates such as semiconductor substrates and thereby produce semiconductor devices.

摘要： In numerous applications of large-area patterning systems, the preferred image magnification is unity. However, in some applications, the size of the substrate may change slightly due to various thermal and/or chemical processing steps. To compensate for scale changes of the substrate, the magnification of the imaging system must vary slightly from unit magnification (typically by a fraction of a percentage) so that a layer already patterned on the substrate will have, after processing, proper image registration with the subsequent layer. This disclosure describes a lithography system for exposing large substrates at high imaging resolution and high exposure throughput, and specifically relates to a scan-and-repeat patterning system that employs a unitary mask-substrate stage and enables projection imaging of a substrate with capability to control the image magnification to compensate for changes of substrate dimensions occurring as a result of previous process steps. A combination of optical and mechanical compensation is used to provide the necessary magnification control, including anamorphic magnification variation in which the fine adjustment is of different magnitudes in x and y dimensions. The optical control is provided by a projection lens with anamorphic magnification adjustment capability. The mechanical compensation is performed by providing a differential relative velocity between the mask and substrate during scanning.

摘要： A lithographic apparatus includes a projection system, which includes a plurality of cubic crystalline optical elements that each impart retardance to a beam of radiation. The optical elements are aligned along an optical axis of the projection system and include two adjacent crystalline optical elements having a common crystalline lattice direction oriented along the optical axis. A first of the two adjacent elements is rotated about the optical axis with respect to a second of the adjacent elements with a predetermined rotation angle. The crystalline optical elements are selected and positioned along the optical axis and the rotation angle is selected such that, for each of two substantially perpendicular polarization states of the beam of radiation having a radiation wavelength of about 193 nm, the patterned beam of radiation has less than about 0.012 waves RMS of wavefront aberration across an exit pupil of the projection system.

摘要： A photolithography tool including an optical system for transmitting a beam of radiation toward a substrate is presented. The optical system includes a plurality of calcium fluoride lens elements, optically transmissive of the beam of radiation, each having respective optical axes and imparting a retardance to the beam. The plurality of calcium fluoride lens elements are aligned along an optical path for propagation of the beam of radiation therethrough. Each of the calcium fluoride lens elements includes a cubic crystalline calcium fluoride that is aligned with its [111] lattice direction, or a lattice direction optically equivalent to the [111] lattice direction, substantially parallel with its optical axis. A first calcium fluoride lens element of the plurality of calcium fluoride lens elements is rotated about its optical axis with respect to a second calcium fluoride lens element. The optical system has less than or about 0.015 waves RMS of wavefront aberration.
