    Abstract: A multilayer mirror for reflecting extreme ultraviolet (EUV) radiation, the mirror comprises a substrate and a stack of layers formed on the substrate. The stack of layers comprises layers comprising a low index material and a high index material, the low index material having a lower real part of the refractive index than the high index material at a given operating wavelength λ. The mirror provides a first peak of reflectivity of 20% or more at a first wavelength λ 1 in a first wavelength band extending from 6 nm to 7 nm and a second peak of reflectivity of 20% or more at a second wavelength λ 2 in a second wavelength band extending from 12.5 nm to 15 nm.

    Abstract: Provided is an X-ray mirror, a method of producing the X-rat mirror, and an X-ray apparatus. The X-ray mirror comprises: a substrate; and an X-ray reflecting structure formed of multiple regions present on the substrate, in which the X-ray reflecting structure comprises a mesostructured film that has the multiple regions having different structural periods in a normal direction of the substrate. Thus, there can be reduced the absorption loss of an X-ray of the mirror that reflects X-rays having different energies.

    Abstract: A method is disclosed for in-situ monitoring of an EUV mirror to determine a degree of optical degradation. The method may comprise the steps / acts of irradiating at least a portion of the mirror with light having a wavelength outside the EUV spectrum, measuring at least a portion of the light after the light has reflected from the mirror, and using the measurement and a pre-determined relationship between mirror degradation and light reflectivity to estimate a degree of multi-layer mirror degradation. Also disclosed is a method for preparing a near-normal incidence, EUV mirror which may comprise the steps / acts of providing a metallic substrate, diamond turning a surface of the substrate, depositing at least one intermediate material overlying the surface using a physical vapor deposition technique, and depositing a multi-layer mirror coating overlying the intermediate material.
