摘要： A method for setting an illumination optical unit involves determining an actual value of an intensity-weighted illumination parameter of the illumination optical unit for multiple field points and for multiple illumination angles. The influence of a deformation of at least one of the optical surfaces of the illumination optical unit on the at least one illumination parameter is then determined. A desired value of the illumination parameter is then predefined. A desired form of the at least one optical surface is determined so that the actual value of the illumination parameter corresponds to the desired value of the illumination parameter within predefined limits. Finally, the optical surface is deformed with the aid of at least one actuator so that an actual form of the optical surface corresponds to the desired form.

摘要： An illumination optical system for EUV microlithography is used to direct an illumination light beam from a radiation source to an object field. At least one EUV mirror has a reflective face with a nonplanar mirror topography for forming the illumination light beam. The EUV mirror has at least one EUV attenuator arranged in front of it. The attenuator face which faces the reflective face of the EUV mirror has an attenuator topography which is designed to complement the mirror topography such that at least sections of the attenuator face are arranged at a constant interval from the reflective face. The result is an illumination optical system in which it is possible to correct unwanted variations in illumination parameters, for example an illumination intensity distribution or an illumination angle distribution, over the object field with as few unwanted radiation losses as possible.

摘要： An illumination optics for EUV microlithography guides an illumination light bundle from a radiation source to an object field with an extension ratio between a longer field dimension and a shorter field dimension, where the ratio is considerably greater than 1. A field facet mirror has a plurality of field facets that set defined illumination conditions in the object field. A following optics downstream of the field facet mirror transmits the illumination light into the object field. The following optics includes a pupil facet mirror with a plurality of pupil facets. The field facets are in each case individually allocated to the pupil facets so that portions of the illumination light bundle impinging upon in each case one of the field facets are guided on to the object field via the associated pupil facet. The field facet mirror not only includes a plurality of basic illumination field facets which provide a basic illumination of the object field via associated basic illumination pupil facets, but also includes a plurality of correction illumination field facets which provide for a correction of the illumination of the object field via associated correction illumination pupil facets. The result is an illumination optics which allows unwanted variations of illumination parameters, for instance an illumination intensity distribution or an illumination angle distribution, to be corrected across the object field.
