摘要： A passivating overcoat bilayer is used for multilayer reflective coatings for extreme ultraviolet (EUV) or soft x-ray applications to prevent oxidation and corrosion of the multilayer coating, thereby improving the EUV optical performance. The overcoat bilayer comprises a layer of silicon or beryllium underneath at least one top layer of an elemental or a compound material that resists oxidation and corrosion. Materials for the top layer include carbon, palladium, carbides, borides, nitrides, and oxides. The thicknesses of the two layers that make up the overcoat bilayer are optimized to produce the highest reflectance at the wavelength range of operation. Protective overcoat systems comprising three or more layers are also possible.

摘要： A method of investigating the location and size of a light-emitting source in a subject is disclosed. In practicing the method, one first obtains a light intensity profile by measuring, from a first perspective with a photodetector device, photons which (i) originate from the light-emitting source, (ii) travel through turbid biological tissue of the subject, and (iii) are emitted from a first surface region of interest of the subject. The light-intensity profile is matched against with a parameter-based biophotonic function, to estimate function parameters such as depth and size. The parameters so determined are refined using data other than the first measured light intensity profile, to obtain an approximate depth and size of the source in the subject. Also disclosed is an apparatus for carrying out the method.

摘要： The present invention provides systems and methods for obtaining a three-dimensional (3D) representation of one or more light sources inside a sample, such as a mammal. Mammalian tissue is a turbid medium, meaning that photons are both absorbed and scattered as they propagate through tissue. In the case where scattering is large compared with absorption, such as red to near-infrared light passing through tissue, the transport of light within the sample is described by diffusion theory. Using imaging data and computer-implemented photon diffusion models, embodiments of the present invention produce a 3D representation of the light sources inside a sample, such as a 3D location, size, and brightness of such light sources.

摘要： A method is provided for repairing defects in a multilayer coating layered onto a reticle blank used in an extreme ultraviolet lithography (EUVL) system. Using high lateral spatial resolution, energy is deposited in the multilayer coating in the vicinity of the defect. This can be accomplished using a focused electron beam, focused ion beam or a focused electromagnetic radiation. The absorbed energy will cause a structural modification of the film, producing a localized change in the film thickness. The change in film thickness can be controlled with sub-nanometer accuracy by adjusting the energy dose. The lateral spatial resolution of the thickness modification is controlled by the localization of the energy deposition. The film thickness is adjusted locally to correct the perturbation of the reflected field. For example, when the structural modification is a localized film contraction, the repair of a defect consists of flattening a mound or spreading out the sides of a depression.
摘要翻译：提供了一种用于修复分层到用于极紫外光刻（EUVL）系统的掩模版坯料上的多层涂层中的缺陷的方法。使用高横向空间分辨率，能量沉积在缺陷附近的多层涂层中。这可以使用聚焦电子束，聚焦离子束或聚焦电磁辐射来实现。吸收的能量将导致膜的结构改性，产生膜厚度的局部变化。通过调节能量剂量可以以亚纳米精度控制膜厚的变化。厚度变化的横向空间分辨率由能量沉积的定位来控制。局部调整膜厚以校正反射场的扰动。例如，当结构改性是局部薄膜收缩时，缺陷的修复包括使平坦化的墩或扩展凹陷的侧面。
