摘要:
A porous member is used in a liquid removal system of an immersion lithographic projection apparatus to smooth uneven flows. A pressure differential across the porous member may be maintained at below the bubble point of the porous member so that a single-phase liquid flow is obtained. Alternatively, the porous member may be used to reduce unevenness in a two-phase flow.

A reflective optical element for a microlithographic projection exposure apparatus, a mask inspection apparatus or the like. The reflective optical element has an optically effective surface, an element substrate (12, 32, 42, 52), a reflection layer system (14, 34, 44, 54) and at least one deformation reduction layer (15, 35, 45, 55, 58). When the optically effective surface (11, 31, 41, 51) is irradiated with electromagnetic radiation, a maximum deformation level of the reflection layer system is reduced in comparison with a deformation level of an analogously constructed reflective optical element without the deformation reduction layer.

The present disclosure provides an apparatus in semiconductor manufacturing. The apparatus includes a mask, a pellicle frame attached to the mask, and a pellicle joined to the pellicle frame thereby forming a sealed enclosure bounded by the pellicle, the pellicle frame, and the mask. The apparatus further includes photo-catalyst particles introduced into the sealed enclosure before the sealed enclosure is formed. The photo-catalyst particles prevent haze formation within the enclosure during lithography exposure processes.

A mirror (1) for a microlithography projection exposure apparatus including a substrate (3) and a reflective coating (5). A functional coating (11) between the substrate (3) and the reflective coating (5) has a local form variation (19) for correcting the surface form of the mirror (1), wherein the local form variation (19) is brought about by a local variation in the chemical composition of the functional coating (11) and wherein a thickness of the reflective coating (5) is not changed by the local variation in the chemical composition of the functional coating (11). The local variation in the chemical composition of the functional coating (11) can be brought about by bombardment with particles (15), for example with hydrogen ions.
摘要:
A method for the production of a mirror element (10) that has a reflective coating (10a) for the EUV wavelength range and a substrate (10b). The substrate (10b) is pre-compacted by hot isostatic pressing, and the reflective coating (10a) is applied to the pre-compacted substrate (10b). In the method, either the pre-compacting of the substrate (10b) is performed until a saturation value of the compaction of the substrate (10b) by long-term EUV irradiation is reached, or, for further compaction, the pre-compacted substrate (10b) is irradiated, preferably homogeneously, with ions (16) and/or with electrons in a surface region (15) in which the coating (10a) has been or will be applied. A mirror element (10) for the EUV wavelength range associated with the method has a substrate (10b) pre-compacted by hot isostatic pressing. Such a mirror element (10) is suitable to be provided in an EUV projection exposure system.

The coating (31) has, in particular for the reflection of EUV radiation, a plurality of layer pairs having alternate layers (33a, 33b) composed of a high refractive index material and a low refractive index material At least one active layer (34) composed of a magnetostrictive material is formed within the reflective coating (31). Also disclosed is an optical element (21) having a substrate (30) and a reflective coating (31). The optical element (21) has at least one first active layer with a material having positive magnetostriction and at least one second active layer with a material having negative magnetostriction. The layer thicknesses and the layer materials of the active layers are such that mechanical stress changes or changes in length of the active layers that are produced by a magnetic field mutually compensate for one another.
