  • Patent number: 6927072
    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: 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.

  • Patent number: 5185073
    Abstract: A separable and reconnectable connection for electrical equipment is provided that is suitable for miniaturization in which vertical interdigitating members integrally attached and protruding from a planar portion are accommodated in control of damage in lateral displacement that occurs on mating with an opposite similar contact. Displacement damage is averted through accommodating lateral stresses by providing one or more of a conformal opposing contact, by strengthening through coating and base reinforcement and a deformable coating. The contacts are fabricated by physical and chemical processes including sputtering, normal and pulse electroplating and chemical vapor deposition. Pulse electroplating of palladium provides a dendritic deposit of uniform height, uniform rounded points and less branching. The contacts on completion are provided with a surrounding immobilizing material that enhances rigidity.
