  • Patent number: 10287698
    Abstract: A non alpha controlled plating bath including Tin species and a trace amount of Polonium species is utilized in a plating tool. The plating tool includes a Polonium filter element to remove Polonium species from the plating bath to selectively plate Tin upon a plating cathode. The filter may include a Titanium inner portion surrounding by a stannic oxide exterior. The filter may reduce the Polonium species by having the polonium absorb and then enter within the stannic oxide matrix. The filter may be located within the plating tool reservoir or filter housing. The filter may be fabricated by forming Tin upon a Titanium backbone and converting the Tin to stannic oxide.

  • Patent number: 8157972
    Abstract: An electrolytic water treatment system improving upon the electrode life of electrolytic oxygen generators by reducing mineral precipitation and fouling that typically occurs in water treatment systems. The electrolytic water treatment system can include a softened water bypass stream into which a flow-through electrolytic element can be positioned. By eliminating exposure of the electrolytic element to hard water, scale formation on electrodes can be significantly reduced such that polarity reversal cycles of the electrolytic element decrease in frequency.

  • Patent number: 4717673
    Abstract: Very stable, polymer-based electrochemical devices, formed by polymerization of thiophene or a derivative such as 3-methylthiophene which is durable in an aqueous electrolyte over a wide pH range, which respond rapidly to chemical or electrical signals, are disclosed. In one embodiment, the device functions as an extremely sensitive sensor which measures changes in chemical concentration or pH. For example, a poly-3-methylthiophene-based device is sensitive to as little as 8.times.10.sup.-16 moles of an oxidant which reversibly interacts with the polymer, including gas phase oxidants such as I.sub.2. In a variation of the polymer-based device, a catalyst such as a noble metal or an enzyme, is dispersed on or within the conducting polymer matrix so that the device is responsive to chemicals such as H.sub.2 and O.sub.2 which the polymer would otherwise respond very slowly to.

  • Patent number: H36
    Abstract: The invention comprises improvements in inert anode electroplating processes that make possible the utilization of typically inexpensive and otherwise advantageous cation-yielding compounds for replenishing the plating bath, compounds that typically are not well suited for such use in prior art systems due to their relatively low dissolution rate which typically requires their use in powder form, and the tendency of the powder particles to aggregate. Exemplary applications for the improved plating process are in Cu-, Ni-, and Pd-plating, and exemplary cation-yielding compounds or CuO, NiO, PdO, Cu(OH).sub.2,Ni(OH).sub.2, and Pd(OH).sub.2. The improvements according to the invention comprise agitating the powder/electrolyte mixture or slurry in a reactor vessel separate from the plating tank, and maintaining the cation concentration in the plating tank within predetermined limits. Agitation typically requires power input to the slurry of at least about 2.
