Introduction Problem Sn-based EUV sources generate Sn debris that contaminates nearby EUV mirrors and thus reduces their reflectivity. Solution Liquid EUV mirrors: grazingincidence mirrors with a liquid metal or alloy surface. The liquid surface absorbs incoming Sn debris while maintaining a low surface roughness and hence a high EUV reflectivity. Applications Dose sensors, reflective debris mitigation tools (e.g. reflective foil trap) and debris-resistant collector optics. Objectives • Measure reflectivity of EUV radiation and ionic Sn debris on liquid metal surface. • Obtain good wetting of liquid metal on metal substrates to enable tilting of the liquid mirror into arbitrary orientation while maintaining a low surface roughness. |
