    Abstract: An EUV collector for collecting and transmitting radiation from an EUV radiation source includes at least one collector mirror for reflecting an emission of the EUV radiation source, which is rotationally symmetric with respect to a central axis. The EUV collector also includes a cooling device for cooling the at least one collector mirror. The cooling device has at least one cooling element, which has a course with respect to the collector mirror, in each case, such that the projection of the course into a plane perpendicular to the central axis has a main direction, which encloses an angle of at most 20° with respect to a predetermined preferred direction. The collector transmits improved quality radiation to illuminate an object field.

    Abstract: A component for setting a scan-integrated illumination energy in an object plane of a microlithography projection exposure apparatus is disclosed. The component includes a plurality of diaphragms which are arranged alongside one another with respect to a direction perpendicular to the scan movement and which differ in their form and the position of which can be altered approximately in the scan direction so that a portion of the illumination energy can be vignetted by at least one diaphragm. The form of the individual diaphragm is specifically adapted to the form of the illumination in a diaphragm plane in which the component is arranged. This has the effect that at least parts of the delimiting edges of two diaphragms always differ in the case of an arbitrary displacement of the diaphragms.

    Abstract: An illumination system for illuminating a mask in a scanning microlithographic projection exposure apparatus has an objective with an object plane, at least one pupil surface and an image plane in which a mask can be arranged. A beam deflection array of reflective or transparent beam deflection elements is provided, where each beam deflection element is adapted to deflect an impinging light ray by a deflection angle that is variable in response to a control signal. The beam deflection elements are arranged in or in close proximity to the object plane of the objective.

    Abstract: An illumination optical unit illuminates an object field using radiation with a first wavelength. The illumination optical unit includes a filter element for suppressing radiation with a second wavelength. The filter element includes at least one component with an obscuring action. As a result of the obscuring action, during operation of the illumination optical unit there is at least one region of reduced intensity of radiation with the first wavelength on a first optical element, arranged downstream of the filter element in the light direction, of the illumination optical unit. The filter element can assume a multiplicity of positions, which lead to different regions of reduced intensity. For each point on an optical used surface of the first optical element, there is at least one position such that the point does not lie in a region of reduced intensity.

    Abstract: A microlithographic projection exposure apparatus (1) comprises an illumination system (4) with an illumination optics (5) for illuminating an illumination field in a reticle plane (6). The illumination optics (5) further includes a light distribution device (12a) which comprises a light deflection array (12) of separate elements and an optical assembly (21, 23 to 26) which converts the light intensity distribution defined by the light distribution device (12a) in a first plane (19) of the illumination optics (5) into an illumination angle distribution in the reticle plane (6). Downstream of an output coupling device (17), which is arranged in the light path between the light deflection array (12) and the reticle plane (6), a space and time resolving detection device (30) is exposed to outcoupled illumination light (31) in such a way that the detection device (30) detects a light intensity distribution corresponding to the light intensity distribution in the first plane (19). The detection device (30) allows the influence of separate elements or groups of separate elements on the light intensity distribution in the first plane (19) to be determined, particularly by varying said separate elements or groups of separate elements over time. The result is an illumination optics in which the function of the light deflection array is performed during normal operation.

    Abstract: A method includes moving a correction device into a neutral position; subsequently ascertaining, for a given arrangement of imaging light channels in the illumination optical unit of the projection exposure apparatus, intensity distributions of at least some of the individual imaging light partial beams along a transverse coordinate transverse to a displacement direction of an object to be imaged; subsequently ascertaining, in dependence on the transverse coordinate, an actual variation of actual values of structure image sizes of object structures in an image field, onto which the object is imaged; and subsequently specifying a predetermined variation of the structure image sizes over the transverse coordinate and displacing correction elements of the correction device, starting from the neutral position, such that the actual variation matches the predetermined variation within a tolerance bandwidth. The method can provide improved imaging results as compared to known uniformity adjustment.
