Abstract:
A projection lens of an EUV-lithographic projection exposure system with at least two reflective optical elements each comprising a body and a reflective surface for projecting an object field on a reticle onto an image field on a substrate if the projection lens is exposed with an exposure power of EUV light, wherein the bodies of at least two reflective optical elements comprise a material with a temperature dependent coefficient of thermal expansion which is zero at respective zero cross temperatures, and wherein the absolute value of the difference between the zero cross temperatures is more than 6K.

Claim (Index 16):
The projection lens of  claim 5 , wherein\n the heated or cooled reflective optical element M k  comprises a material with a temperature dependent coefficient of thermal expansion which is zero at a zero cross temperature T 0k  which is different from the predefined temperature of the temperature sensitive element; wherein the predefined temperature of the temperature sensitive element is at a reference temperature T Ref ; wherein the material with a zero cross temperature T 0k  varies regarding its real value of the zero cross temperature due to manufacturing, resulting in a manufacturing tolerance \u0394T 0k  such that the real value of the zero cross temperature is within the interval T 0k \u00b1\u0394T 0k , and wherein the zero cross temperature T 0k  is higher than an increased maximum of a reference temperature T Ref  and the respective average or maximum temperature based on the spatial temperature distribution \u0394T k (x,y,z) and added by the reference temperature (\u0394T kav +T Ref  or \u0394T kmax +T Ref ), the maximum is increased by the absolute value of the manufacturing tolerance \u0394T 0k , expressed as T 0k >max(T Ref , \u0394T kav +T Ref )+|\u0394T 0k |, T 0k >max(T Ref , \u0394T kmax +T Ref )+|\u0394T 0k |.
