  • Publication number: 20150147481
    Abstract: A method for making a scissoring type current-perpendicular-to-the-plane magnetoresistive sensor with exchange-coupled soft side shields uses oblique angle ion milling to remove unwanted material from the side edges of the upper free layer. All of the layers making up the sensor stack are deposited as full films. The sensor stack is then ion milled to define the sensor side edges. The side regions are then refilled by deposition of an insulating layer. Next, the lower soft magnetic layers of the exchange-coupled side shields are deposited, which also coats the insulating layer up to and past the side edges of the upper free layer. The soft magnetic material adjacent the side edges of the upper free layer is removed by oblique angle ion beam milling. The material for the antiparallel-coupling (APC) layers is deposited, followed by deposition of the material for the upper soft magnetic layers of the exchange-coupled side shields.

    Abstract: 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.

  • Patent number: 7771578
    Abstract: In a method for production of a corrosion resistant and/or oxidation resistant coating, at least one metal of the platinum group or an alloy thereof is galvanically deposited onto a surface of a substrate, and thereafter the thusly galvanically coated substrate is aluminized. In a first stage of the galvanic deposition process a current magnitude applied for the galvanizing is increased continuously or step-wise beginning from an initial value up to a maximum value, and in a second stage of the galvanic deposition process the current magnitude applied for the galvanizing is maintained constant at the maximum value. The galvanic deposition of the or each metal of the platinum group or the corresponding alloy may be carried out using an open-celled or open-mesh or porous anode.

  • Publication number: 20100195292
    Abstract: When silver oxide is reduced to silver, a large number of cores of metallic silver are formed inside the silver oxide. Then, the silver oxide is reduced in a manner of being hollowed out while its original outer configuration is being maintained. As a result, the curvature of the silver generated becomes larger. The utilization of this microscopic-particle implementation mechanism allows accomplishment of the bonding even if the silver oxide is supplied not in a particle-like configuration, but in a closely-packed layer-like configuration. In the present invention, there is provided an electronic member including an electrode for inputting/outputting an electrical signal, or a connection terminal for establishing a connection with the electrical signal, wherein the uppermost surface of the electrode or the connection terminal is a silver-oxide layer.
