Operation at high current density, using at least a diamond anode, provides for higher current efficiency, extended lifetime operation, and improved cost efficiency. High current density operation, in either a single pass or recycle mode, provides for rapid generation of oxidants, with high current efficiency, which potentially allows for more compact systems. Beneficially, operation in reverse polarity for a short cleaning cycle manages scaling, provides for improved efficiency and electrode lifetime and allows for use of impure feedstocks without requiring water softeners. Systems have application for generation of chlorine or other oxidants, including mixed oxidants providing high disinfection rate per unit of oxidant, e.g. for water treatment to remove microorganisms or for degradation of organics in industrial waste water.

  • Patent number: 10167382
    Abstract: The invention relates to a sealing material, to a gas seal made of this sealing material, and to a method for the production of such a gas seal made of this sealing material. The sealing material contains a bromobutyl elastomer in an amount of 100 parts by weight, a filler material in an amount between 10 and 100 parts by weight for setting the volume of the sealing material, a curing agent in an amount between 0.5 and 3.0 parts by weight for curing the sealing material, and a cross-linking component in an amount between 0.1 and 2.0 parts by weight for bringing about a peroxidic cross-linking of the sealing material. This sealing material permits a particularly high vacuum-tightness (that is to say, a low leakage rate) in comparison to sealing materials according to the state of the art, and accounts for resistance, on the one hand, to aggressive gases and, on the other hand, to pump oils such as, for instance, perfluoropolyethene oil or silicon oil.

  • Patent number: 10128102
    Abstract: Disclosed are pre-wetting apparatus designs and methods for cleaning solid contaminants from substrates prior to through resist deposition of metal. In some embodiments, a pre-wetting apparatus includes a process chamber having a substrate holder, and at least one nozzle located directly above the wafer substrate and configured to deliver pre-wetting liquid (e.g., degassed deionized water) onto the substrate at a grazing angle of between about 5 and 45 degrees. In some embodiments the nozzle is a fan nozzle configured to deliver the liquid to the center of the substrate, such that the liquid first impacts the substrate in the vicinity of the center and then flows over the center of the substrate. In some embodiments the substrate is rotated unidirectionally or bidirectionally during pre-wetting with multiple accelerations and decelerations, which facilitate removal of contaminants.

  • Patent number: 10053792
    Abstract: Disclosed herein are cups for engaging wafers during electroplating in clamshell assemblies and supplying electrical current to the wafers during electroplating. The cup can comprise an elastomeric seal disposed on the cup and configured to engage the wafer during electroplating, where upon engagement the elastomeric seal substantially excludes plating solution from a peripheral region of the wafer, and where the elastomeric seal and the cup are annular in shape, and comprise one or more contact elements for supplying electrical current to the wafer during electroplating, the one or more contact elements attached to and extending inwardly towards a center of the cup from a metal strip disposed over the elastomeric seal. A notch area of the cup can have a protrusion or an insulated portion on a portion of a bottom surface of the cup where the notch area is aligned with a notch in the wafer.

  • Patent number: 10014170
    Abstract: An apparatus for electroplating metal on a semiconductor substrate with improved plating uniformity includes in one aspect: a plating chamber configured to contain an electrolyte and an anode; a substrate holder configured to hold the semiconductor substrate; and an ionically resistive ionically permeable element comprising a substantially planar substrate-facing surface and an opposing surface, wherein the element allows for flow of ionic current towards the substrate during electroplating, and wherein the element comprises a region having varied local resistivity. In one example the resistivity of the element is varied by varying the thickness of the element. In some embodiments the thickness of the element is gradually reduced in a radial direction from the edge of the element to the center of the element. The provided apparatus and methods are particularly useful for electroplating metal in WLP recessed features.

  • Patent number: 10006763
    Abstract: A device that helps to properly align and install large pistons in cylinders is disclosed. Large pistons and cylinders are heavy and difficult to handle, and if the piston is not inserted in the cylinder perfectly in line with the length of the cylinder, damage results. The device holds both the piston and cylinder being assembled, and has a number of alignment mechanisms. A laser is also used to set up the device and to ensure that the piston is straight with the center line of the cylinder for proper alignment and insertion.

  • Patent number: 9988734
    Abstract: Disclosed are cup assemblies for holding, sealing, and providing electrical power to a semiconductor substrate during electroplating which may include a cup bottom element having a main body portion and a moment arm, an elastomeric sealing element disposed on the moment arm, and an electrical contact element disposed on the elastomeric sealing element. The main body portion may be such that it does not substantially flex when a substrate is pressed against the moment arm, and it may be rigidly affixed to another feature of the cup structure. The ratio of the average vertical thickness of the main body portion to that of the moment arm may be greater than about 5. The electrical contact element may have a substantially flat but flexible contact portion disposed upon a substantially horizontal portion of the sealing element. The elastomeric sealing element may be integrated with the cup bottom element during manufacturing.

  • Patent number: 9845251
    Abstract: The present invention concerns a method for reducing the amount of polluting and/or valuable elements through application of electrolysis, in particular of the electrocapturing phenomenon. The electrolysis according to the present invention is applied permanently over time in a polluted water body. The predetermined action area (115bis, 115ter) preferably has a smaller extension than the water body. The at least one phenomenon (125bis, 125ter) is preferably powered electrically through production of electrical energy in loco through at least one renewable energy source (140). The method is suitable for purifying large expanses of water, like seas, lakes, lagoons and rivers, through plants operating permanently, however this does not rule out other applications.
