Abstract:
An EUV collector for use in an EUV projection exposure apparatus includes at least one mirror surface having surface structures for scattering a used EUV wavelength (λ) of used EUV light. The mirror surface has a surface height with a spatial wavelength distribution between a lower limit spatial wavelength and an upper limit spatial wavelength. An effective roughness (rmsG) below the lower limit spatial wavelength (PG) satisfies the following relation: (4 π rmsG cos(θ)/λ)2<0.1. θ denotes an angle of incidence of the used EUV light at the mirror surface. The following applies to an effective roughness (rmsGG′) between the lower limit spatial wavelength (PG) and the upper limit spatial wavelength (PG′): 1.5 rmsG<rmsGG′<6 rmsG.

Claim (Index 16):
The illumination system of  claim 15 , wherein the EUV collector is arranged in a near-field fashion in relation to a field plane that is conjugate to the object plane.
