  • Patent number: 7402529
    Abstract: A method of fabricating a cladding region for use in MRAM devices includes the formation of a conductive bit line proximate to a magnetoresistive memory device. The conductive bit line is immersed in a first bath containing dissolved ions of a first conductive material for a time sufficient to displacement plate a first barrier layer on the conductive line. The first barrier layer is then immersed in an electroless plating bath to form a flux concentrating layer on the first barrier layer. The flux concentrating layer is immersed in a second bath containing dissolved ions of a second conductive material for a time sufficient to displacement plate a second barrier layer on the flux concentrating layer.

  • Publication number: 20070048589
    Abstract: A micro fuel cell and method of forming such on a substrate (12) is provided that derive power from a three dimensional fuel/oxidant interchange. The fuel cell includes a plurality of porous pedestals (17) formed on the substrate (12), each porous pedestal (17) including an anode (68), a cathode (70) surrounding the anode (68); and an electrolyte (60) filling a cavity between the anode (68) and the cathode (70). The cathode (70) is accessible to ambient air, and the anode (68) has a passageway (30) thereto for receiving a fuel. The anode (68) and cathode (70) may be formed by etching a cavity for the electrolyte (60) or by forming trenches (58, 66) to form each anode (68) and cathode (70), wherein each trench (66) between an anode and cathode is filled with electrolyte.

    Abstract: A method for fabricating a cladded conductor (42) for use in a magnetoelectronics device is provided. The method includes providing a substrate (10) and forming a conductive barrier layer (12) overlying the substrate (10). A dielectric layer (16) is formed overlying the conductive barrier layer (12) and a conducting line (20) is formed within a portion of the dielectric layer (16). The dielectric layer (16) is removed and a flux concentrator (30) is formed overlying the conducting line (20).

  • Publication number: 20050095855
    Abstract: Methods and compositions are provided for the electroless deposition of NiFe on a work piece. A deposition solution for use in electroless deposition of NiFe on a work piece is formed from a nickel ion source, a ferrous iron source, a complexing agent, a reducing agent, and a pH adjusting agent. The deposition solution is substantially free from alkali metal ions. A method for fabricating a flux concentrating system for use in a magnetoelectronics device begins by providing a work piece and forming an insulating material layer overlying the work piece. A trench is formed in an insulating layer and a barrier layer is deposited within the trench. A NiFe cladding layer is deposited overlying the barrier layer. After depositing the NiFe cladding layer, the insulating material layer proximate to the trench has a concentration of alkali metal ions less than about 1×1011 atoms/cm2.
