Sub-diffraction-limited resolution and high contrast thin flat silver superlenses (Ag, Ag/Ni and Ag/Ge) are engineered through refining interfacial roughness to reduce scattering loss. A smooth interface is a key factor for realizing high performance superlens lithography while the seed layer effect is detrimental. This report verifies that a superlens is a potential tool for nano-photolithography.
