    摘要: An illumination system of a microlithographic projection exposure apparatus includes a beam deflection array including a number beam deflection elements, for example mirrors. Each beam deflection element is adapted to deflect an impinging light beam by a deflection angle that is variable in response to control signals. The light beams reflected from the beam deflection elements produce spots in a system pupil surface. The number of spots illuminated in the system pupil surface during an exposure process, during which a mask is imaged on a light sensitive surface, is greater than the number of beam deflection elements. This may be accomplished with the help of a beam multiplier unit that multiplies the light beams reflected from the beam deflection elements. In another embodiment the beam deflecting elements are controlled such that the irradiance distribution produced in the system pupil surface changes between two consecutive light pulses of an exposure process.

    摘要: The disclosure relates to an EUV microlithography projection exposure apparatus having an exposure light source for producing radiation in a first spectral range from 5 nm-15 nm, and a heat light source for producing radiation in a second spectral range from 1-50 μm. The apparatus also includes an optical system having a first group of mirrors for guiding radiation from the first spectral range along a light path such that each mirror in the first group can have a first associated intensity distribution applied to it in the first spectral range during operation of the exposure light source. The heat light source is arranged such that at least one mirror in the first group can have a second associated intensity distribution in the second spectral range applied to it during operation of the heat light source. The first intensity distribution differs from the second intensity distribution essentially by a position-independent factor.
