    Abstract: 微細光学像生成素子(100)は、準結晶パターンを同一平面上で少なくとも二つ以上組み合わせた配置パターンに基づいて複数の開口部(140)が配置された微細構造部(120)を備える。微細構造部(120)は、レーザ光を遮断する遮光膜(130)と、遮光膜(130)に設けられ、レーザ光を通過可能な複数の開口部(140)と、を備えてもよい。準結晶パターンは、例えば、準結晶の格子構造の一つであるペンローズタイルの格子点からなるパターンであってもよい。

    Abstract: Disclosed are methods and apparatus for facilitating an inspection of a sample using an optical inspection tool. An optical inspection tool is used to obtain an optical image or signal from an EUV reticle that specifies an intensity variation across the EUV reticle, and this intensity variation is converted to a CD variation that removes a flare correction CD variation so as to generate a critical dimension uniformity (CDU) map without the flare correction CD variation. This removed flare correction CD variation originates from design data for fabricating the EUV reticle, and such flare correction CD variation is generally designed to compensate for flare differences that are present across a field of view (FOV) of a photolithography tool during a photolithography process. The CDU map is stored in one or more memory devices and/or displayed on a display device, for example, of the inspection tool or a photolithography system.

    Abstract: A self-powered 'near field' lithographic system 100 includes three primary components, namely, a thin film or emitter substrate 110 including a radioactive material (e.g., a radioisotope 112), a target substrate 120 which carries an energy-modifiable layer 122 (e.g., photo-resist) and a stencil (e.g., 130) that is either positioned between the emitter and target substrates fabricated upon and defined in the emitter substrate. The stencil is made from a material capable of blocking particles emitted through radioactive decay from the radioisotope of the emitter substrate. The stencil includes openings or vias 132 patterned to permit selective transmission of the particles emitted through radioactive decay from the radioisotope of the emitter substrate 110, and the stencil is preferably placed up against (or very close to) the target substrate 120.
