摘要： The disclosure relates to an optical projection arrangement that can be used to image a reticle onto a substrate. The projection arrangement includes reflective elements, by which a ray path is defined. A combination stop is in a pupil of the ray path. The combination stop has a first opening (aperture opening) for use as an aperture stop. The combination stop also has a second opening for allowing passage of a ray bundle of the ray path, such that the combination stop acts as a combined aperture stop and stray light stop. In addition, the disclosure relates to a corresponding combination stop for optical arrangements, as well as related systems, components and methods.

摘要： The disclosure provides an optical system having an optical axis, where the optical system includes a polarization manipulator which includes first and second subelements. The first subelement has a non-planar, optically effective surface. For light passing through the first subelement, the first subelement causes a change in the polarization state. A maximum effective retardation introduced by the first subelement along the optical axis is less than a quarter of the working wavelength of the optical system. The first subelement and the second subelement have mutually facing surfaces which are mutually complementary. The optical system also includes a position manipulator to manipulate the relative position of the first and second subelements.

摘要： A catadioptric projection objective has a multiplicity of lenses and at least one concave mirror, and also two deflection mirrors in order to separate a partial beam path running from the object field to the concave mirror from the partial beam path running from the concave mirror to the image field. The deflection mirrors are tilted relative to the optical axis of the projection objective about tilting axes running parallel to a first direction (x-direction). The first deflection mirror is arranged in optical proximity to a first field plane and the second deflection mirror is arranged in optical proximity to a second field plane, which is optically conjugate with respect to the first field plane. A displacement device for the synchronous displacement of the deflection mirrors is provided. The deflection mirrors have different local distributions of their reflection properties in first and second reflection regions, respectively.

摘要： Another approach to decrease the resolution is to introduce an immersion liquid having high refractive index into the gap that remains between a final lens element on the image side of the projection objective and the photoresist or another photosensitive layer to be exposed. Projection objectives that are designed for immersion operation and are therefore also referred to as immersion objective may reach numerical apertures of more than 1, for example 1.3 or 1.4. The term “immersion liquid” shall, in the context of this application, relate also to what is commonly referred to as “solid immersion”. In the case of solid immersion, the immersion liquid is in fact a solid medium that, however, does not get in direct contact with the photoresist but is spaced apart from it by a distance that is only a fraction of the wavelength used. This ensures that the laws of geometrical optics do not apply such that no total reflection occurs.
摘要翻译： 降低分辨率的另一种方法是将具有高折射率的浸没液体引入保留在投影物镜的像侧上的最终透镜元件与待曝光的光致抗蚀剂或另一光敏层之间的间隙中。 为浸入式操作设计的投影物镜，因此也称为浸没物镜，可达到大于1，例如1.3或1.4的数值孔径。 在本申请的上下文中，术语“浸没液体”还涉及通常称为“固体浸没”的内容。 在固体浸渍的情况下，浸没液实际上是固体介质，然而，其不会与光致抗蚀剂直接接触，而是与其隔开距离，其仅是所使用波长的一部分。 这确保几何光学的定律不适用于不发生全反射。
