EUV Optics Overview

Glancing to normal incidence optics for 13.5 nm (EUV)

EUVL is used extensively in high-volume manufacturing of memory and logic integrated circuits. Mo/Si multilayers, optimized for EUV, with protective cap layers of various designs are available from Rigaku for use in collection, beam conditioning pre-reticle for scanners and beam conditioning pre-sample and imaging post-sample for metrology.
