Paper Abstract

The utilization of oxide mixtures as layer material for coating design has been transferred to the ion beam sputtering technology and was applied to high-reflecting as well as anti-reflecting components at the wavelength of 193nm. Exclusively, the oxides SiO2 and Al2O3 are candidates for appropriate thin film designs below 200nm. Experimental data received from laser-calorimetric measurements, spectroscopic investigations and laser-induced damage tests are presented for several specimens. With respect to state-of-the-art thin film deposition in the DUV spectral range, conventional quarterwave designs have also been characterized and will be compared to the sputtered mixed oxide coatings.
