Multilayer coatings for the EUVL process development tool
SPIE ProceedingsEmerging Lithographic Technologies IX(2005)
摘要
Reported is a summary of the coating of three elements of the illuminator and three of the projection optics of the EUVL Process Development Tool. The coating process used is e-beam evaporation in combination with low energy ion beam smoothening. The reflectance of the coatings, which are covered with a special protective capping layer, is typically around 65% and the non correctable figure error that is added by the full multilayer stack is controlled to better than 15 picometer.
