20100314258 | Electrochemical Fabrication Processes Incorporating Non-Platable Metals and/or Metals that are Difficult to Plate On - Embodiments are directed to electrochemically fabricating multi-layer three dimensional structures where each layer comprises at least one structural and at least one sacrificial material and wherein at least some metals or alloys are electrodeposited during the formation of some layers and at least some metals are deposited during the formation of some layers that are either difficult to electrodeposit and/or are difficult to electrodeposit onto. In some embodiments, the hard to electrodeposit metals (e.g. Ti, NiTi, W, Ta, Mo, etc.) may be deposited via chemical or physical vacuum deposition techniques while other techniques are used in other embodiments. In some embodiments, prior to electrodepositing metals, the surface of the previously formed layer is made to undergo appropriate preparation for receiving an electrodeposited material. Various surface preparation techniques are possible, including, for example, anodic activation, cathodic activation, and vacuum deposition of a seed layer and possibly an adhesion layer. | 12-16-2010 |
20110031126 | ELECTROCOATING PROCESS FOR MIXED-METAL AUTOMOTIVE BODIES-IN-WHITE - Mixed-metal automotive vehicle bodies-in-white comprising ferrous metal surfaces, zinc surfaces, aluminum alloy surfaces, and magnesium alloy surfaces are cleaned and immersed in an aqueous bath comprising an adhesion promoter and an aqueous electrocoat bath (the adhesion promoter may be in the electrocoat bath. The adhesion promoter, which may be a cerium salt, is selected to react with each metal in the body surfaces to form an oxide layer that provides corrosion resistance for the surface and adherence for the deposited polymeric paint coating. The body is cathodic in the electrocoat deposition. | 02-10-2011 |
20110272287 | METHOD FOR PATTERNING MAGNETIC FILMS - A method of patterning magnetic devices and sensors by double etching, which includes forming a layer of dielectric on a substrate; depositing a thin adhesion layer and a thin seed layer; applying a thin resist frame to pattern a structure; cleaning the metal surface to prepare for plating; electroplating to fill up the structure and the uncovered field area, which uses a paddle cell with a permanent magnet providing magnetic field to induce magnetic orientation; stripping the resist frame; etching the seed layer/adhesion layer exposed below the resist frame down to the dielectric surface; etching the rest of magnetic materials and the seed layer using electrolytic etching in the field; etching the adhesion layer in the field, and repeating the steps for building structures with multiple levels. | 11-10-2011 |
20120067734 | PHENOL CROSSLINK FOR SENSOR MEMBRANE - Embodiments herein provide a membrane that is a product of a phenol crosslinked with one or more compounds containing an allyl group. The phenol may be electropolymerized with the allyl-containing compounds to form the crosslinked polymer. Suitable allyl-containing compounds include allylphenol, allylalcohol, allylamine, and allylcarbamide. A membrane may have one type of allyl-containing compound, or, alternatively, two or more types of compounds. As used in an analyte sensing device, a membrane formed from a crosslinked phenol may provide improved interference exclusion, peroxide response, stability, and/or solvent resistance. | 03-22-2012 |
