    摘要: The disclosure relates to an illumination system of a microlithographic projection exposure apparatus. The illumination system can include a depolarizer which in conjunction with a light mixing system disposed downstream in the light propagation direction at least partially causes effective depolarization of polarized light impinging on the depolarizer. The illumination system can also include a microlens array which is arranged upstream of the light mixing system in the light propagation direction. The microlens array can include a plurality of microlenses arranged with a periodicity. The depolarizer can be configured so that a contribution afforded by interaction of the depolarizer with the periodicity of the microlens array to a residual polarization distribution occurring in a pupil plane arranged downstream of the microlens array in the light propagation direction has a maximum degree of polarization of not more than 5%.

    摘要: 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.

    摘要: In general, in one aspect, the disclosure features an illumination system for a microlithographic projection exposure apparatus configured so that during operation the illumination system illuminates a reticle plane of the microlithographic projection exposure apparatus with light of a desired polarization distribution. The illumination system includes a first polarization-influencing optical element and a second polarization-influencing optical element. During operation the first polarization-influencing optical element converts a first polarization distribution produced by a light source unit into a second polarization distribution which is different from the first polarization distribution. The second polarization-influencing optical element converts the second polarization distribution into a third polarization distribution corresponding to the desired polarization distribution, the second polarization-influencing optical element causing an effective rotation of the preferred polarization direction through 90° over its optically effective surface.

    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.
