Patent number: 11842871Abstract: The switch contacts of a MEMS relay for a circuit interrupter are coated with a thin layer of liquid metal, and the MEMS relay is disposed in a sealed enclosure containing a gas medium. The gas medium provides an environmentally desirable alternative to sulfur hexafluoride (SF6), prevents oxidation of the liquid metal coating the relay switch contacts, and has sufficient dielectric strength in order to prevent current flow after separation of the switch contacts.Type: GrantFiled: September 15, 2021Date of Patent: December 12, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Stanislav Kadlec, Sandy Omar Jimenez Gonzalez, Venkat raman Thenkarai Narayanan, Mykhailo Gnybida, Christian Ruempler

Patent number: 11380530Abstract: A method and apparatus for sputter depositing an insulation layer onto a surface of a cavity formed in a substrate and having a high aspect ratio. A target formed from a material to be included in the insulation layer and the substrate are provided in a substantially enclosed chamber defined by a housing. A plasma is ignited within the substantially enclosed chamber and a magnetic field is provided adjacent to a surface of the target to contain the plasma adjacent to the surface of the target. A voltage is rapidly increased to repeatedly establish high-power electric pulses between a cathode and an anode. An average power of the electric pulses is at least 0.1 kW, and can be much greater. An operational parameter of the sputter deposition is controlled to promote sputter depositing of the insulation layer in a transition mode between a metallic mode and a reactive mode.Type: GrantFiled: August 24, 2020Date of Patent: July 5, 2022Assignee: EVATEC AGInventors: Juergen Weichart, Stanislav Kadlec, Mohamed Elghazzali

Patent number: 9587306Abstract: For producing a directional layer for instance with constant nominal directionality, such as a low-retentivity layer with a preferred direction of magnetization or a support layer for such a layer by cathode sputtering on a substrate surface (4), the coating process takes place in a manner whereby particles emanating from a target surface (6) impinge predominantly from directions whose projections onto the substrate surface (4) lies within a preferred angular range surrounding the nominal direction. This is achieved for instance by positioning a collimator (8), encompassing plates (9) that extend at a normal angle to the substrate surface (4) parallel to the nominal direction in front of the substrate surface (4), but in lieu of or in addition to such positioning the location or movement of the substrate surface (4) relative to the target surface (6) can also be suitably adjusted or controlled.Type: GrantFiled: January 2, 2008Date of Patent: March 7, 2017Assignee: EVATEC AGInventors: Hartmut Rohrmann, Hanspeter Friedli, Jürgen Weichart, Stanislav Kadlec, Martin Dubs

Patent number: 8475634Abstract: A method of magnetically enhanced sputtering an electrically-conductive material onto interior surfaces of a trench described herein includes providing a magnetic field adjacent to a target formed at least in part from the electrically-conductive material, and applying a DC voltage between an anode and the target as a plurality of pulses. A high-frequency signal is applied to the pedestal supporting the semiconductor substrate to generate a self-bias field adjacent to the semiconductor substrate. The high-frequency signal is applied to the pedestal in pulses, during periods of time that overlap with the periods during which the DC voltage pulses are applied. The periods of time that the high-frequency signals are applied include a duration that extends beyond termination of the DC voltage pulse applied between the anode and the target. During each DC voltage pulse the electrically-conductive material is sputter deposited onto the side walls of the trench formed in the semiconductor substrate.Type: GrantFiled: October 24, 2008Date of Patent: July 2, 2013Assignee: OC Oerlikon Balzers AFInventors: Jurgen Weichart, Stanislav Kadlec
