Abstract

Extreme ultraviolet (EUV) emission from Xe plasma in the λ=13.5 nm band is theoretically investigated for lithographic application. It appears that a large number of satellite lines due to the 4d-4f, 4d-5p, and 4p-4d transitions significantly contribute to the emission over the spectral range from 10 to 17 nm. At electron densities above 1020 cm3, laser-produced Xe plasmas attain quasilocal thermodynamic equilibrium (LTE) in order to make the emission intensity in the 13.5 nm band comparable to that in the 11 nm band.
