Online re-optimization of optical filters on a production sputter tool

引用

Chinese Optics Letters 2013年第13期11卷 46-47页

作者： Stephan Waldner Patrick Biedermann Silvia Schwyn Th6ny Evatec Ltd. Lochrietstrasse 14 CH-8890 Flums Switzerland

This contribution presents a magnetron sputter deposition tool with broadband optical monitor and online re-optimization capability for high volume production. The layer termination relies on a comparison of the actually measured reflection spectrum with a pre-calculated target spectrum. Spectra recorded after each deposited layer are analyzed by the re-optimization module and in case of significant deviations layer thicknesses and target spectra for the remaining layers are recalculated. This technique significantly improves the performance and reproducibility in case of highly denlanding coating designs and is able to correct abnormal production errors in individual layers, which will lead to coating failure without re- optimization.
