Abstract:
The disclosure relates to a method for producing an illumination system for an EUV apparatus in and to an illumination system for an EUV apparatus

Claim (Index 1):
A method for producing an illumination system for an EUV apparatus, the illumination system being configured so that, during operation of the EUV apparatus, the illumination system receives EUV radiation of an EUV radiation source at a source position in an entrance plane and shapes, from a portion of the received EUV radiation, illumination radiation that is directed into an illumination field in an exit plane of the illumination system, the illumination field fulfilling an illumination specification, the method comprising:\n installing mirror modules of the illumination system at installation positions provided for the mirror modules to establish an illumination beam path which extends from the source position to the illumination field, the mirror modules comprising a first mirror module comprising a first facet mirror at a first installation position and a second mirror module comprising a second facet mirror at a second installation position of the illumination system; coupling measurement light into the illumination beam path at an input coupling position upstream the mirror module that is first along the illumination beam path; detecting measurement light after reflection of the measurement light at each of the mirror modules of the illumination beam path; ascertaining current measurement values for at least one system measurement variable from detected measurement light, the current measurement values representing a current state of the system measurement variable of the illumination system; ascertaining correction values from the current measurement values using sensitivities that represent a relationship between the system measurement variable and a change in the orientation of at least one mirror module in its installation position; and adjusting at least one mirror module with variation of the orientation of the mirror module in the installation position in degrees of freedom of a rigid body using the correction values to change the current state in a manner such that in the case of irradiation with EUV radiation from the EUV radiation source, the illumination radiation in the illumination field fulfills the illumination specification, wherein the method further comprises:\n demounting the first mirror module from its installation position; \n removing the first mirror module from the illumination system; \n installing a third mirror module in place of the first mirror module into the installation position; and \n adjusting the third mirror module by changing an orientation of the mirror module in the installation position in degrees of freedom of a rigid body.
