Abstract
Extreme UV lithography is one of the most favoured options for the next generation of lithography systems, being considered as one of the keys of the 50 nm technology node. ZrN/TiN, multi-layered coatings for mirrors with high reflectivity at grazing incidence for EUV radiation (13.5) are proposed as coatings for the collection mirror in an EUVL system. These films were deposited on different substrates (Si, glass, and different metals) by d.c. magnetron sputtering and characterized by XRD, AES, EDX, AFM and EUV reflectivity using synchrotron radiation.
