Publication number: 20210222297Abstract: Provided is a method for protecting a complex watch component against gaseous environment, characterized in that the entire surface of the complex watch component or parts of said surface is/are coated with a protective coating, which is not visible by observation with the naked eye, by atomic layer deposition (ALD). Further provided are a method for obtaining a complex watch component, and a complex watch component comprising a protective ALD coating.Type: ApplicationFiled: March 22, 2021Publication date: July 22, 2021Inventors: Cyriaque Boccard, Xavier Multone, Pierre Di Luna, Alexandra Roulet

Patent number: 9909218Abstract: A method and apparatus for local beam processing using a beam activated gas to etch material are described. Compounds are disclosed that are suitable for beam-induced etching. The invention is particularly suitable for electron beam induced etching of chromium materials on lithography masks. In one embodiment, a polar compound, such as ClNO2 gas, is activated by the electron beam to selectively etch a chromium material on a quartz substrate. By using an electron beam in place of an ion beam, many problems associated with ion beam mask repair, such as staining and riverbedding, are eliminated. Endpoint detection is not critical because the electron beam and gas will not etch significantly the substrate.Type: GrantFiled: January 12, 2010Date of Patent: March 6, 2018Assignee: Ecole Polytechnique Federales de LausanneInventors: Tristan Bret, Patrik Hoffmann, Michel Rossi, Xavier Multone

Publication number: 20150136210Abstract: Solar devices with high resistance to light-induced degradation are described. A wide optical bandgap interface layer positioned between a p-doped semiconductor layer and an intrinsic semiconductor layer is made resistant to light-induced degradation through treatment with a hydrogen-containing plasma. In one embodiment, a p-i-n structure is formed with the interface layer at the p/i interface. Optionally, an additional interface layer treated with a hydrogen-containing plasma is formed between the intrinsic layer and the n-doped layer. Alternatively, a hydrogen-containing plasma is used to treat an upper portion of the intrinsic layer prior to deposition of the n-doped semiconductor layer. The interface layer is also applicable to-multi-junction solar cells with plural p-i-n structures. The p-doped and n-doped layers can optionally include sublayers of different compositions and different morphologies (e.g., microcrystalline or amorphous).Type: ApplicationFiled: May 10, 2013Publication date: May 21, 2015Inventors: Xavier Multone, Daniel Borrello, Stefano Benagli, Johannes Meier, Ulrich Kroll, Marian Fecioru-Morariu
