Lithography lens
WebIn very few lens systems is image distortion as critical as in microlithography. Since the distortion in a lithographic objective is measured in nanometers, the common technique of using the chief ray to define image placement is not sufilcient. The centroid of a ray bundle gives a more accurate prediction of the actual lens distortion. Figure ... WebThe Starlith 1700i is the first ZEISS lithography system in which the optics are constructed from lenses and mirrors (refractors and reflectors) (catadioptric). In …

This paper presents the design, analysis, and testing of a high-precision two-degrees-of-freedom compliant mechanism to be used for lens XY micro-adjustment.
WebA superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit.The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution depending on the illumination wavelength and the numerical aperture NA of the objective lens. Many lens designs have been proposed that go … WebThis method, called immersion lithography, is the current cutting edge of practical production technology. It works because numerical aperture is a function of the …
