Abstract:
A projection optical unit for EUV projection lithography has a plurality of mirrors for imaging an object field into an image field with illumination light. At least one of the mirrors is an NI mirror and at least one of the mirrors is a GI mirror. A mirror dimension Dx of the at least one NI mirror in a plane of extent (xz) perpendicular to a plane of incidence (yz) satisfies the following relationship: 4  LLWx/IWPV max <Dx.  A mirror dimension Dy of the at least one GI mirror in the plane of incidence (yz) satisfies the following relationship: 4  LLWy /( IWPV max  cos( a ))< Dy.

Claim (Index 10):
A method of using a projection exposure apparatus comprising an illumination optical unit, an imaging optical unit and an EUV light source, the method comprising:\n using the illumination optical unit to illuminate a reticle with light generated by the EUV light source; and using the projection optical unit to project at least a portion of the illuminated ret- icle onto a light-sensitive layer, wherein the projection optical unit comprises a projection optical unit according to  claim 1 .
