  • Patent number: 9017526
    Abstract: The disclosed embodiments relate to methods and apparatus for removing material from a substrate. In various implementations, conductive material is removed from a sidewall of a previously etched feature such as a trench, hole or pillar on a semiconductor substrate. In practicing the techniques herein, a substrate is provided in a reaction chamber that is divided into an upper plasma generation chamber and a lower processing chamber by a corrugated ion extractor plate with apertures therethrough. The extractor plate is corrugated such that the plasma sheath follows the shape of the extractor plate, such that ions enter the lower processing chamber at an angle relative to the substrate. As such, during processing, ions are able to penetrate into previously etched features and strike the substrate on the sidewalls of such features. Through this mechanism, the material on the sidewalls of the features may be removed.

  • Publication number: 20110122543
    Abstract: A method and apparatus for anodizing a porous valve metal pellet in a flowing liquid electrolyte is described. The apparatus comprises an insulative container comprised of a lower region, a central region including a cavity for holding the pellet, an upper region, and a continuous passageway extending through the lower, central, and upper regions. Lower and upper screens serving as lower and upper electrodes are disposed in the passageway in the lower and upper container regions, respectively. During anodizing, the electrolyte flows through the lower container region including the lower screen, the porous pellet and then the upper container region including the upper screen. The lower and upper screens are at an opposite electrical polarity as the pellet so that a dielectric oxide is formed on the exposed valve metal including interior portions of the pellet that are exposed to the flowing electrolyte.

  • Patent number: 7871508
    Abstract: A mediated electrochemical oxidation process and apparatus are used to process biological and organic materials to provide hydrogen and oxygen for use as fuel in numerous types of equipment. Waste materials are introduced into an apparatus for contacting the waste with an electrolyte containing the oxidized form of one or more reversible redox couples, at least one of which is produced electrochemically by anodic oxidation at the anode of an electrochemical cell. The oxidized species of the redox couples oxidize the organic waste molecules and are themselves converted to their reduced form, whereupon they are reoxidized and the redox cycle continues until all oxidizable waste species have undergone the desired degree of oxidation. The entire process takes place at temperatures to avoid any possible formation of either dioxins or furans. The oxidation process may be enhanced by the addition of ultrasonic energy and/or ultraviolet radiation.

  • Patent number: 7857951
    Abstract: The present invention intends to provide a water purification apparatus that is small and easy-to-use, yet being capable of efficiently creating flocs of impurities and removing the impurities from the wastewater in a single pass. To achieve this objective, an inner tubular anode 12 made of stainless steel or carbon is inserted into an outer tubular cathode 11 made of aluminum, leaving a predetermined intermediate space 13 between them, and electrolysis is carried out to produce aluminum hydroxide. The aluminum hydroxide thus produced serves as the medium for flocculating the impurities in the wastewater ascending the intermediate space 13. The wastewater containing the flocs of impurities is filtrated with a filter 18 within a filtering and settling tank 17. As a result, the impurities are completely removed from the wastewater.

  • Publication number: 20100314263
    Abstract: Provided is a standalone integrated water treatment system for a distributed water supply. A filter input receives water to be treated. A coagulation system is in operative connection with the filter input, wherein the water which has been filtered is subjected to a coagulation process performed by the coagulation system to create pin floc from suspensions in the water. A maturation buffer tank is in operative connection with the coagulation system, wherein floc is aggregated in size within the water. A spiral separator is in operative connection with the maturation buffer tank, and the water is separated into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is in operative connection with the spiral separator and is configured to receive the first stream of water and to perform a filtration operation on the first stream of water.

  • Publication number: 20100181190
    Abstract: A process encompassing hydrogen and oxygen gases as a partial fuel source when utilized together with a fossil-based fuel to power conventional internal combustion engines. Hydrogen and oxygen gases are produced by electrolysis in an electrolyser unit(s), on-demand and on-board a vehicle, or in stationary applications, eliminating the need of highly-pressurized hydrogen storage tanks When said gases are introduced into the combustion chamber of the engine, via the air intake assembly, they increase the efficiency of the combustion burn by enriching the air to fuel ratio, resulting in a reduction of the fossil-based fuels required for optimum engine performance, said gases effectively becoming a partial hybrid fuel source. The process includes scalability for all size and types of installations, cold-weather applications and longer operating capabilities. As an additional benefit, in direct correlation, this process reduces carbon dioxide emissions, and, in varying quantities, other greenhouse gas emissions.
