The present disclosure provides masks suitable for Extreme Ultraviolet (EUV) and X-ray lithography by including a non-reflective region within the reflective multilayer. This non-reflective region replaces a typical absorber layer used to provide the pattern for integrated circuits. New classes of materials and associated components for use in devices and systems operating at ultraviolet (UV), extreme ultraviolet (EUV), and/or soft X-ray wavelengths are described. This disclosure relates to an EUV Photomask Architecture comprising of reflective and non reflective regions eliminating the need for an absorber layer, the effects of shadows on masks, 3D diffraction effects, and defect management. Such a material structure and combination may be used to make components such as mirrors, lenses or other optics, panels, lightsources, photomasks, photoresists, or other components for use in applications such as lithography, wafer patterning, astronomical and space applications, biomedical applications, or other applications.
