  • Patent number: 8337676
    Abstract: A high performance TMR sensor is fabricated by incorporating a tunnel barrier having a Mg/MgO/Mg configuration. The 4 to 14 Angstroms thick lower Mg layer and 2 to 8 Angstroms thick upper Mg layer are deposited by a DC sputtering method while the MgO layer is formed by a NOX process involving oxygen pressure from 0.1 mTorr to 1 Torr for 15 to 300 seconds. NOX time and pressure may be varied to achieve a MR ratio of at least 34% and a RA value of 2.1 ohm-um2. The NOX process provides a more uniform MgO layer than sputtering methods. The second Mg layer is employed to prevent oxidation of an adjacent ferromagnetic layer. In a bottom spin valve configuration, a Ta/Ru seed layer, IrMn AFM layer, CoFe/Ru/CoFeB pinned layer, Mg/MgO/Mg barrier, CoFe/NiFe free layer, and a cap layer are sequentially formed on a bottom shield in a read head.

  • Patent number: 8303785
    Abstract: A plasma processing apparatus includes a chamber, substrate stage, electrode, conductive members, and deposition shield. The chamber is maintained at a predetermined potential. The substrate stage serves to hold a substrate within the chamber. The electrode serves to generate a plasma inside the chamber by applying AC power to the chamber. The conductive members connect the substrate stage and the side wall of the chamber by surrounding the plasma space between the substrate stage and the electrode in plasma formation, and at least some of them are separated by being moved by a driving mechanism so as to form an opening for loading a substrate onto the substrate stage while no plasma is being formed. The deposition shield covers the surfaces of the conductive members on the side of the plasma space.

  • Patent number: 8298385
    Abstract: A method and an apparatus are provided in which non-directional and directional metal (e.g. Ni) deposition steps are performed in the same process chamber. A first plasma is formed for removing material from a target; a secondary plasma for increasing ion density in the material is formed in the interior of an annular electrode (e.g. a Ni ring) connected to an RF generator. Material is deposited non-directionally on the substrate in the absence of the secondary plasma and electrical biasing of the substrate, and deposited directionally when the secondary plasma is present and the substrate is electrically biased. Nickel silicide formed from the deposited metal has a lower gate polysilicon sheet resistance and may have a lower density of pipe defects than NiSi formed from metal deposited in a solely directional process, and has a lower source/drain contact resistance than NiSi formed from metal deposited in a solely non-directional process.
