    摘要: An optical element serves to influence a nominal beam angle, preset over a beam cross-section, of a radiation beam (26) hitting the optical element. The optical element has a spatial optical structure (16) which generates a first part of the influence exerted on the nominal beam angle when exposed to the radiation beam (26). An optical coating (24) applied on the spatial optical structure or on a carrier layer carrying the spatial optical structure (16) causes a defined attenuation of parts of the radiation beam (26) when exposed to the latter, thus resulting in a second part of the influence exerted on the nominal beam angle. The optical effects of the structure (16) and the coating (24) are such that they complement each other in influencing the nominal beam angle. The manufacturing effort required to obtain this effect is quite low. Moreover, this leads to new possibilities in terms of influencing the nominal beam angle.

    摘要: There is an illumination optical apparatus capable of forming an intensity distribution profile of light in an exit pupil that is substantially symmetrical with respect to an axis or substantially symmetrical and substantially identical in shape in two perpendicular directions with respect to an axis to illuminate an illumination surface under desired illumination conditions. The illumination optical apparatus includes a first fly's-eye optical system (18a) having first optical components and a second fly's-eye optical system (18b) having second optical components arranged in parallel in one-to-one correspondence to the first optical components. An illumination surface (M) is illuminated with light from each of the second optical components in an overlapping manner. The correspondence relationship between the first optical components and the second optical components is established so that an intensity distribution profile of light in an exit pupil of the illumination optical apparatus is substantially symmetrical with respect to an axis or substantially symmetrical and substantially identical in shape in two perpendicular directions with respect to an axis.

    摘要: An illumination system (190) for a microlithography projection exposure apparatus (100) for illuminating an illumination field (165) with the light from a primary light source (102) has a variably adjustable pupil shaping unit (150) for receiving light from the primary light source (102) and for generating a variably adjustable two-dimensional intensity distribution in a pupil shaping surface (110) of the illumination system. The pupil shaping unit (150) has a Fourier optical system (500) for converting an entrance beam bundle (105) entering through an entrance plane of the Fourier optical system into an exit beam bundle exiting from an exit plane of the Fourier optical system. The Fourier optical system has a focal length f
    FOS and a structural length L measured between an entrance-side first system surface and an exit-side last system surface along an optical axis and the condition (L/f
    FOS )

    摘要: An illumination system for a micro-lithographic contact and proximity exposure apparatus comprising a light source (1), a collector (2), two optical integrators (3,6), two Fourier lenses (4,7), at least one angle defining element (5); and at least one field lens (8). The first optical integrator (3) comprises optical sub-elements and produces a plurality of secondary light sources (6a) each emitting a light bundle. A first Fourier lens (7) effects a superposition of the light bundles and uniform irradiance in its Fourier plane (4a). The second optical integrator (6) is located at the Fourier plane (7a) of the first Fourier lnes (7), comprises optical sub-elements and produces a plurality of tertiary light sources (6a) each emitting a light bundle. A second Fourier lens (7) effects a superposition of the light bundles, uniform irradiance and a desired and uniform angular distribution of light illuminating a mask (9) for contact or proximity lithographic printing. The field lens (8) in the Fourier plane (7a) ensures telecentric illumination the mask (9). The optional field lens (12) in the Fourier plane (4a) of the first optical integrator (3) ensures telecentric illumination of the second optical integrator (6). The angle defining element (5) comprises optical sub-elements and defines the angular distribution of the light illuminating the mask (9). A change of the position of the second Fourier lens (7) or the use of a Fourier zoom lens (62) or hybrid Fourier lens (63) allows run-out control (registration error correction) of the lateral dimensions of the printed miniature pattern in the resist layer on the surface of the wafer (10).

    摘要: In an illumination system using mirrors, the facets of a field facet mirror focus plural source images on respective facets of a pupil facet mirror to perform the function of an integrator. A facet masking means is provided for selectively blocking facets of the filed or pupil facet mirrors. The facet masking means has a grid selectively interposable in the projection beam to provide intermediate illumination settings. The grid has a spacing smaller than the source images but larger than the wavelength of the projection beam so that there is no diffraction.

    摘要: An illumination apparatus is arranged to illuminate a surface to be illuminated M with illumination light emitted from a light source 5. The illumination apparatus includes an incidence-side reflection-type fly-eye optical system 12 having multiple reflection-type partial optical systems arranged in rows, an emission-side reflection-type fly-eye optical system 14 having multiple reflection-type partial optical systems arranged in rows such that the multiple reflection-type partial optical systems in the emission-side reflection-type fly-eye optical system respectively correspond to the multiple reflection-type partial optical systems in the incidence-side reflection-type fly-eye optical system 12, and a condensing optical system including two reflecting mirrors 18, 20 that guide illumination light, reflected by the emission-side reflection-type fly-eye optical system 14, to the surface to be illuminated M. At least one of the two reflecting mirrors has a center of curvature that is optically eccentric with respect to a normal to the surface to be illuminated M at the center of the illuminated region.
