  • Patent number: 9567665
    Abstract: Provided is a sputtering target containing SiO2 for a magnetic recording film, wherein a ratio of the peak intensity of cristobalites, which are crystallized SiO2, to the background intensity (cristobalite peak intensity/background intensity) in an X-ray diffraction is 1.40 or less. The present invention aims to obtain a sputtering target for a magnetic recording film capable of inhibiting the formation of cristobalites in the target which cause the generation of particles during sputtering, and shortening the burn-in time.

  • Patent number: 9530629
    Abstract: The invention relates to a method and apparatus for the generation of multilayered coatings onto substrates. Typically the apparatus used is a closed field unbalanced magnetron configuration in conjunction with one or more cylindrical and rotatable shields and a substrate carrier on which the substrates to be coated are carried. The shields and substrate holder are provided for rotation about a common axis of rotation. The shields are provided with apertures to allow the selective positioning of the apertures to define a passage or passages along which material from the targets can pass onto the substrates. The targets can be cleaned prior to the coating stage by operation of the targets with the shields selectively positioned to prevent the deposited material from reaching the substrates.

  • Patent number: 9478394
    Abstract: In a sputter deposition tool (100) of the type in which an ion source (101) generates a beam directed at a sputtering target, the sputtering target comprises an elongated exterior skirt (102) and a generally circular insert (103) positioned within the skirt, the surfaces of the skirt and insert being relatively coplanar and forming the surface of the target, with the elongated dimension of the skirt being axially oriented toward the ion source. The insert is rotated within the skirt to one of several positions during use of the target by the sputter deposition tool, to distribute wear of the target around the rotating insert and thus increase the utilization and useful life of the overall target assembly.

  • Patent number: 9449632
    Abstract: A method for manufacturing a magnetic recording medium including at least a non-magnetic substrate, a soft magnetic underlayer, an orientation control layer that controls an orientation of an immediate upper layer, and a perpendicular magnetic layer in which a magnetization easy axis is mainly perpendicularly oriented with respect to the non-magnetic substrate so as to be laminated one another on the non-magnetic substrate. The perpendicular magnetic layer includes two or more magnetic layers, and each layer is subjected to a crystal growth such that each crystal grain composing each magnetic layer forms a columnar crystal continuous in a thickness direction together with the crystal grains composing the orientation control layer. The orientation control layer, formed of a Co—Cr alloy, is formed by the reactive sputtering using a mixture of a sputtering gas and nitrogen.

  • Patent number: 9443697
    Abstract: A carbonaceous material is removed using a low energy focused ion beam in the presence of an etch-assisting gas. Applicant has discovered that when the beam energy of the FIB is lowered, an etch-assisting gas, such as O2, greatly increases the etch rate. In one example, polyimide material etched using a Xe+ plasma FIB with a beam energy from 8 keV to 14 keV and O2 as an etch-assisting gas, the increase in etch rate can approach 30× as compared to the default mill rate.
