    摘要: An illumination system for a microlithographic projection exposure step-and-scan apparatus has a light source, a first optical raster element and a second optical raster element. The first optical raster element extends in a first pupil plane of the illumination system and is designed such that the geometrical optical flux of the system is increased perpendicular to a scan direction of the projection exposure apparatus. The second optical raster element extends in a second pupil plane of the illumination system, which is not necessarily different from the first pupil plane, and is designed such that the geometrical optical flux of the system is increased in the scan direction and perpendicular thereto. This makes it possible to improve the irradiance uniformity in a reticle plane.

    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.

    摘要: A device for adjusting the illumination dose on a photosensitive layer in a microlithographic projection exposure apparatus has a plurality of stop elements which are, in a direction perpendicularly to a scanning direction of the apparatus, arranged next to one another. Each stop element has an outer surface that absorbs substantially all projection light impinging thereon, and a substantially rectangular circumference. Each stop element furthermore has at least one recess in its circumference or at least one opening through which projection light is allowed to pass. A drive unit individually displaces the stop elements along the scanning direction into a light field.
