    摘要: A method is disclosed for improving an optical imaging property, for example spherical aberration or the focal length, of a projection objective of a microlithographic projection exposure apparatus. First, an immersion liquid is introduced into an interspace between a photosensitive surface and an end face of the projection objective. Then an imaging property of the projection objective is determined, for example using an interferometer or a CCD sensor arranged in an image plane of the projection objective. This imaging property is compared with a target imaging property. Finally, the temperature of the immersion liquid is changed until the determined imaging property is as close as possible to the target imaging property.

Methods can include performing a first exposure to image a first sub-pattern of the pattern, where the first sub-pattern includes a plurality of first features extending in a first direction and spaced apart essentially periodically at a predominant periodicity length P in a second direction perpendicular to the first direction. The first exposure can be performed using a multipolar illumination mode that includes at least one substantially dipolar intensity distribution having two illumination poles positioned on a pole orientation axis substantially parallel to the second direction and spaced apart from each other. The poles of the dipolar intensity distribution can each have an azimuthal width defined by a pole angle θ, and a pole area APOLE according to: 0.6

    摘要: An illumination system for illuminating a mask in a microlithographic exposure apparatus has an optical axis and a pupil surface. The system can include an array of reflective or transparent beam deflection elements such as mirrors. Each deflection element can be adapted to deflect an impinging light ray by a deflection angle that is variable in response to a control signal. The beam deflection elements can be arranged in a first plane. The system can further include an optical raster element, which includes a plurality of microlenses and/or diffractive structures. The beam deflection elements), which can be arranged in a first plane, and the optical raster element, which can be arranged in a second plane, can commonly produce a two-dimensional far field intensity distribution. An optical imaging system can optically conjugate the first plane to the second plane.
