Abstract: An optical system includes multiple cubic crystalline optical elements and one or more uniaxial birefringent elements in which the crystal lattices of the cubic crystalline optical elements are oriented with respect to each other to reduce the effects of intrinsic birefringence and produce a system with reduced retardance. The net retardance of the system is reduced by the cancellation of retardance contributions from the multiple cubic crystalline optical elements and the uniaxial birefringent element. The optical system may be used in a photolithography tool to pattern substrates such as semiconductor substrates and thereby produce semiconductor devices.

Abstract: An illumination system and condenser for use in photolithography in the extreme ultraviolet wavelength region has a first non-imaging optic element collecting electromagnetic radiation from a source and creates a desired radiance distribution. A second non-imaging optic element receives the electromagnetic radiation from the first non-imaging optic element and redirects and images the electromagnetic radiation. The electromagnetic radiation from the second non-imaging optic element is suitable for being received by other conventional optical surfaces to provide a desired radiance distribution with a desired angular distribution and desired shape. Facets are used to provide the desired illumination over the desired illumination field. Reflective facets may be placed on the second non-imaging optic, which can reduce the number of mirrors and increase efficiency.
