Patent number: 7261957Abstract: A multilayer system and its production. Multilayer systems, such as those used as mirrors in the extreme ultraviolet wavelength range, suffer contamination or oxidation during storage in air and in long-time operation, i.e. when exposed to EUV radiation in a vacuum environment with certain partial pressures of water or oxygen, which causes a serious reduction in reflectivity. The multilayer system according to the invention will have a long life with constantly high reflectivity. Their reflectivity can be enhanced by barrier layers. The multilayer systems according to the invention have protective layers comprising iridium. The multilayer systems according to the invention are produced by direct, ion-beam-supported growth of the respective layer. The multilayer systems according to the invention are not only resistant to contamination and oxidation, but can also be cleaned if necessary, without losing reflectivity.Type: GrantFiled: November 12, 2003Date of Patent: August 28, 2007Assignee: Carl Zeiss SMT AGInventors: Frederik Bijkerk, Eric Louis, Andrey E.

Patent number: 7223479Abstract: In certain example embodiments, a multi-layer undercoat may include a layer of or including tin oxide on the glass surface and a layer of silicon nitride thereover. Tin oxide is advantageous in that it is relatively durable, and is a low stress material with excellent adhesion to glass. Moreover, the sputtering rate for tin oxide is several times higher than that of silicon nitride. Thus, problems of high cost (due to slow deposition rate) and durability (due to high compressive stress) can be overcome through the use of tin oxide as a bottom portion of the dual layer overcoat. The coated article may or may not be heat treated in different embodiments of the invention.Type: GrantFiled: September 29, 2003Date of Patent: May 29, 2007Assignee: Guardian Industries Corp.Inventor: Grzegorz Stachowiak

Patent number: 7217461Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, a sub-oxide layer (e.g., NiCrOx) may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity, and good coloration to be achieved.Type: GrantFiled: September 1, 2004Date of Patent: May 15, 2007Assignees: Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.
