Abstract: A facet mirror is to be used as a bundle-guiding optical component in a projection exposure apparatus for microlithography. The facet mirror has a plurality of separate mirrors. For individual deflection of incident illumination light, the separate mirrors are in each case connected to an actuator in such a way that they are separately tiltable about at least one tilt axis. A control device, which is connected to the actuators, is configured in such a way that a given grouping of the separate mirrors can be grouped into separate mirror groups that include in each case at least two separate mirrors. The result is a facet mirror which, when installed in the projection exposure apparatus, increases the variability for setting various illumination geometries of an object field to be illuminated by the projection exposure apparatus. Various embodiments of separate mirrors for forming the facet mirrors are described.

Abstract: A device serves for reflecting electromagnetic waves, in particular in a length range less than 200 nm. It has a mirror carrier made of a material with at least approximately vanishing thermal expansion and at least one reflective layer applied on said mirror carrier. An intermediate layer made of a material which is formed such that its surface roughness is not significantly increased after beam processing methods is fitted between the mirror carrier and the reflective layer.

Abstract: An EUV optical projection system includes at least six reflecting surfaces for imaging an object (OB) on an image (IM). The system is preferably configured to form an intermediate image (IMI) along an optical path from the object (OB) to the image (IM) between a secondary mirror (M2) and a tertiary mirror (M3), such that a primary mirror (M1) and the secondary mirror (M2) form a first optical group (G1) and the tertiary mirror (M3), a fourth mirror (M4), a fifth mirror (M5) and a sixth mirror (M6) form a second optical group (G2). The system also preferably includes an aperture stop (APE) located along the optical path from the object (OB) to the image (IM) between the primary mirror (M1) and the secondary mirror (M2). The secondary mirror (M2) is preferably concave, and the tertiary mirror (M3) is preferably convex. Each of the six reflecting surfaces preferably receives a chief ray (CR) from a central field point at an incidence angle of less than substantially 15°. The system preferably has a numerical aperture greater than 0.18 at the image (IM). The system is preferably configured such that a chief ray (CR) converges toward the optical axis (OA) while propagating between the secondary mirror (M2) and the tertiary mirror (M3).

Abstract: A projection objective formed from six mirrors arranged in a light path between an object plane and an image plane is provided. The projection objective, in some examples, is characterized by having a physical distance between the vertexes of adjacent mirrors that is large enough to allow for the six mirrors to have sufficient thickness and stability properties to prevent surface deformations due to high layer tensions. In some embodiments, mirror thickness are such that surface deformations are prevented with mirrors having layer tensions lower than 350 MPa. Mirror surfaces may comprise multilayer systems of Mo/Be or Mo/Si layer pairs. In some examples, the physical distance between a vertex of the third mirror and a vertex of the sixth mirror (S3S6) satisfies the following relationship: 0.3×(a used diameter of the third mirror S3+a used diameter of the sixth mirror S6)
