  • Publication number: 20090325320
    Abstract: A process for reconditioning a multi-component electrode comprising a silicon electrode bonded to an electrically conductive backing plate is provided. The process comprises: (i) removing metal ions from the multi-component electrode by soaking the multi-component electrode in a substantially alcohol-free DSP solution comprising sulfuric acid, hydrogen peroxide, and water and rinsing the multi-component electrode with de-ionized water; (ii) polishing one or more surfaces of the multi-component electrode following removal of metal ions there from; and (iii) removing contaminants from silicon surfaces of the multi-component electrode by treating the polished multi-component electrode with a mixed acid solution comprising hydrofluoric acid, nitric acid, acetic acid, and water and by rinsing the treated multi-component electrode with de-ionized water. Additional embodiments of broader and narrower scope are contemplated.

  • Publication number: 20090322199
    Abstract: A carrier assembly is provided comprising a backside mounted electrode carrier and electrode mounting hardware. The backside mounted electrode carrier comprises an electrode accommodating aperture, which in turn comprises a sidewall structure that is configured to limit lateral movement of an electrode positioned in the aperture. The electrode accommodating aperture further comprises one or more sidewall projections that support the weight of an electrode positioned in the aperture. The electrode mounting hardware is configured to engage an electrode positioned in the electrode accommodating aperture from the backside of the carrier and urge the electrode against the sidewall projections so as to limit axial movement of the electrode in the electrode accommodating aperture. Additional embodiments of broader and narrower scope are contemplated.

  • Publication number: 20090060798
    Abstract: A method measures a property of a germicidal solution in an endoscope processor spectroscopically by placing a quantity of the solution into a cuvette and passing a light therethrough. A reservoir receives a quantity of the solution and bubbles are filtered out via a cross-flow filter prior to putting a sample therefrom into the cuvette for measuring.

  • Publication number: 20080236618
    Abstract: Methods of cleaning plasma processing chamber components include contacting surfaces of the components with a cleaning solution, while avoiding damage of other surfaces or areas of the components by the cleaning solution. An exemplary plasma processing chamber component to be cleaning is an elastomer bonded electrode assembly having a silicon member with a plasma-exposed silicon surface, a backing member, and an elastomer bonding material between the silicon surface and the backing member.

  • Publication number: 20080193434
    Abstract: A self-directed and self-assembled nanomedicine of quantized conductive junction and its preparation process are introduced. In the present disclosure, bio-organic medicine proteins are prepared into a quantized conductive junction with a nanostructure quantum dot and a polymer monolayer on an inorganic silicon surface by seven cooperative modes; and the preparation process of this inorganic-organic-biological hetero-polymer nano-structure component with free radical electrons, aromatic hetercycle structures, bio-fluorescence, and redox bioactivity is consist of making unitary, binary, ternary, and/or quaternary liquid biochemical medicines ingredients of an antioxidase antioxidant, a ?-adrenergic receptor agonist, a P2-purinergic receptor agonist, and/or a phenylalkylamine calcium channel blocker into a solid state quantized conductance junctions using L 6(2)15 and L9(3)4 orthogonal protocol.

  • Publication number: 20080166333
    Abstract: ABSTRACT A bi-stable quantum wire array of self-assembled nano-medicine and its process present in the invention. The bi-stable quantum wire array with quantum bit and kondo effect is prepared by self-assembling an oxygen radical antagonist of antioxidase, a ?-receptor agonist, a P2 receptor agonist, a calcium antagonist of phenyl alkyl amines, and/or a nucleotide monomer of purines and its binary, ternary, quaternary or quinary compounds and using the interaction of inelastic electron tunneling. The invention not only benefits mechanisms-targeted multifunctional device discoveries, but also profits inventions of nanometer structures, novel materials, quantum calculation devices, biosensors and quantum bit magnetic random access memories (MRAM).

  • Patent number: 7079399
    Abstract: A printed circuit board having improved solder pads for preventing from short circuit of the printed circuit board caused by axial leads (30, 31) of components engaging the circuit surrounding the soldering pad comprises a pair of through holes (10, 11), a pair of first pads (20, 21) surrounding corresponding through holes and a pair of second pads (40, 41) adjacent corresponding first pads. When components are inserted into the through holes of the printed circuit board using placement machines, bent portions of the axial leads that are extended out of the first pads will fall into the second pads.

  • Patent number: 6752916
    Abstract: A method for determining an end point of a planarization process for removing metal from a surface of a substrate submerged in an electrolytic solution or slurry. A first electrode is provided which is operable to contact the surface of the substrate, such as a working electrode of a potentiostat system. A second electrode is provided which is operable to contact the electrolytic solution, such as a reference electrode of the potentiostat system. The first electrode is contacted to the surface of the substrate and an electrochemical property is measured, such as the electrochemical potential between the first and second electrodes, where the electrochemical property is indicative of an electrochemical characteristic of the substrate-slurry system. The planarization process is preferably stopped when a substantial change in the electrochemical potential of the system is measured.
