  • Patent number: 9493880
    Abstract: An electric current is passed through an acidic solution containing one or more soluble metal salts in an electrolytic cell divided by an anion exchange membrane. The acidic solution is fed into the cathode compartment whereby the passage of electric current at sufficient voltage causes the generation of hydrogen at the cathode. This gives rise to a localized very highly polarized region at the cathode resulting in a localized effective high relative pH. This causes the metal cation species to precipitate as a hydroxide (or oxide) species and electroadsorption/electrocoagulation causes the finely precipitated hydroxide (or oxide) species to adhere to the cathode. Electrodialytic transport of the liberated acid anions across the anion exchange membrane selectively removes the acid anions. Oxygen and hydrogen ions are formed by hydrolysis as the counter-reaction at the anode. Hydrogen ions combine with the anions to regenerate sulfuric acid.

Techniques include a processing tank containing an anolyte fluid, and one or more plating cells each having a catholyte fluid compartment with a circulation path that connects to a separate or remote catholyte reservoir. Thus, with such a configuration, a single pump can be used to flow catholyte (via manifolds) through one or more plating cells. Thus, with the catholyte reservoir maintained off board, instead of dumping catholyte over a weir into a reservoir, catholyte fluid—after flowing through a plating cell—is returned to the catholyte reservoir.

    Abstract: A wafer processing apparatus is disclosed that includes a wafer support and a processing base. The wafer support is configured to support a wafer at a processing position with respect to a processing base. The processing base includes a scroll pump oriented to pump a processing fluid in a substantially perpendicular direction with respect to the surface of the wafer when the wafer contacts the processing fluid while in the processing position. While in contact with the processing fluid, the wafer support may rotate the wafer in the processing fluid. In one embodiment, the diameter of the scroll pump is substantially the same as or greater than the diameter of the surface of the wafer being processed.

  • Publication number: 20140166476
    Abstract: The embodiments disclosed herein relate to methods and apparatus for promoting bubble-free circulation of processing fluids in a recirculation system. Certain disclosed techniques involve passive, mechanical valve designs that promote variable resistance to flow in a drain. Other techniques involve automated flow control schemes that utilize feedback from flow meters, level sensors, etc. to achieve a balanced and bubble-free flow. The disclosed embodiments greatly reduce the incorporation of gas into a processing fluid, in particular as the processing fluid returns from a processing cell to a reservoir.

  • Patent number: 8747647
    Abstract: In a process for chlorine-alkali electrolysis, use is made of an oxygen depletion cathode. The process is run with a high excess of oxygen. The oxygen needed for this is provided for a device of the gas separation, for example a VPSA plant or an air fractionation plant. The large quantities of oxygen produced lead to considerable costs of the process. According to the invention, the oxygen-rich atmosphere remaining after passing through the process is fed back into the device for gas separation as input gas. The device the gas separation is therefore operated with an oxygen-rich input gas and therefore produces a larger quantity of oxygen-rich gas, which in turn is fed to the oxygen depletion cathode. As a result of the circulation of the gas, the economy of the overall process is increased considerably.
