Abstract

Debris mitigation is still a critical issue for the development of extreme ultraviolet projection lithography (EUVL). Here, we describe the analysis of the efficiency of the debris-mitigation system (DMS) presently in use in the laser–plasma–source micro-exposure tool (MET) operating at the Frascati ENEA Research Center. Basic to such an analysis is a code specifically developed for processing the images of debris-flux-exposed glass slides. The code stands out as a tool for further plasma debris-related analyses.
