  • Patent number: 8329249
    Abstract: Although dots and servo patterns are made of the same magnetic material, the dots have a relatively low coercive force so as to allow data deletion and rewrite by a magnetic head, while the servo patterns have a high coercive force compared with the coercive force of the dots. The coercive force of the servo patterns is strong enough so as to eliminate the influence of shape magnetic anisotropy.

  • Patent number: 8227773
    Abstract: A glitch duration threshold is determined based on an allowable dose uniformity, a number of passes of a workpiece through an ion beam, a translation velocity, and a beam size. A beam dropout checking routine repeatedly measures beam current during implantation. A beam dropout counter is reset each time beam current is sufficient. On a first observation of beam dropout, a counter is incremented and a position of the workpiece is recorded. On each succeeding measurement, the counter is incremented if beam dropout continues, or reset if beam is sufficient. Thus, the counter indicates a length of each dropout in a unit associated with the measurement interval. The implant routine stops only when the counter exceeds the glitch duration threshold and a repair routine is performed, comprising recalculating the glitch duration threshold based on one fewer translations of the workpiece through the beam, and performing the implant routine starting at the stored position.

  • Publication number: 20120177808
    Abstract: Direct resistive heating is used to grow nanotubes out of carbon and other materials. A growth-initiated array of nanotubes is provided using a CVD or ion implantation process. These processes use indirect heating to heat the catalysts to initiate growth. Once growth is initiated, an electrical source is connected between the substrate and a plate above the nanotubes to source electrical current through and resistively heat the nanotubes and their catalysts. A material source supplies the heated catalysts with carbon or another material to continue growth of the array of nanotubes. Once direct heating has commenced, the source of indirect heating can be removed or at least reduced. Because direct resistive heating is more efficient than indirect heating the total power consumption is reduced significantly.

  • Patent number: 8158215
    Abstract: A method of manufacturing magnetic recording media with a high areal recording density, in which there write bleeding during magnetic recording is eliminated by reducing insofar as possible the coercive force and remanent magnetization in areas between magnetic tracks, is provided. The method of manufacture can produce magnetic recording media 10, in which a magnetic layer 3 is provided on at least one surface of a nonmagnetic substrate 1, and a magnetically separated magnetic pattern 3a is formed in this magnetic layer 3; by implanting atoms into the magnetic layer 3 with a uniform distribution in the thickness direction of the magnetic layer 3, and partially rendering nonmagnetic the magnetic layer 3, nonmagnetic portions 5 which magnetically separate the magnetic pattern 3a are formed.

    Abstract: A system and method for maintain a desired degree of platen flatness is disclosed. A laser system is used to measure the flatness of a platen. The temperature of the platen is then varied to achieve the desired level of flatness. In some embodiments, this laser system is only used during a set up period and the resulting desired temperature is then used during normal operation. In other embodiments, a laser system is used to measure the flatness of the platen, even while the workpiece is being processed.

  • Patent number: 8153466
    Abstract: A method of fabricating a workpiece is disclosed. A material defining apertures is applied to a workpiece. A species is introduced to the workpiece through the apertures and the material is removed. For example, the material may be evaporated, may form a volatile product with a gas, or may dissolve when exposed to a solvent. The species may be introduced using, for example, ion implantation or gaseous diffusion.

  • Publication number: 20120080407
    Abstract: The present invention provides a plasma ion beam system that includes multiple gas sources and that can be used for performing multiple operations using different ion species to create or alter submicron features of a work piece. The system preferably uses an inductively coupled, magnetically enhanced ion beam source, suitable in conjunction with probe-forming optics sources to produce ion beams of a wide variety of ions without substantial kinetic energy oscillations induced by the source, thereby permitting formation of a high resolution beam.

  • Publication number: 20120070741
    Abstract: Provided are battery electrode structures that maintain high mass loadings (i.e., large amounts per unit area) of high capacity active materials in the electrodes without deteriorating their cycling performance. These mass loading levels correspond to capacities per electrode unit area that are suitable for commercial electrodes even though the active materials are kept thin and generally below their fracture limits. A battery electrode structure may include multiple template layers. An initial template layer may include nanostructures attached to a substrate and have a controlled density. This initial layer may be formed using a controlled thickness source material layer provided, for example, on a substantially inert substrate. Additional one or more template layers are then formed over the initial layer resulting in a multilayer template structure with specific characteristics, such as a surface area, thickness, and porosity.

  • Patent number: 8133553
    Abstract: A process for forming a ceramic layer comprising a compound of a metal on a deposition surface of a workpiece comprises providing a reactive gas, selecting the amounts of a vapor of the metal and ions of the metal relative to each other, generating the metal vapor, and projecting an ion beam of the metal ions. The metal vapor, the metal ions, and the reactive gas form the ceramic layer with a desired structure. The process may include the step of controlling a deposition surface temperature. In one embodiment, the metal vapor comprises zirconium vapor and the ion beam comprises zirconium ions. The relative amounts of the zirconium vapor and the zirconium ions are selected to form a zirconia ceramic layer on the deposition surface. The zirconia may have multiple crystal phases that are formed according to a predetermined ratio.

  • Patent number: 8119208
    Abstract: There is disclosed an apparatus and method for focused electric field enhanced plasma-based ion implantation. The apparatus includes an implantation chamber, a vacuum pump for maintaining the pressure in the implantation chamber at a desired level, a sample holder, means for applying a negative potential to the sample holder, and means for supplying a gaseous or vaporized implantation material. The supplying means takes the form of a feed conduit having an exit opening located in the implantation chamber above the sample holder, and when a negative potential is applied to the sample holder the exit opening of the feed conduit is maintained at a potential that is positive relative to the sample holder.

  • Publication number: 20120034419
    Abstract: Methods of forming microelectronic structures using multilayer processes are disclosed. The methods comprise the use of a developer-soluble protective layer adjacent the substrate surface in a multilayer stack to protect the substrate during pattern transfer. After etching, the pattern is transferred into the developer-soluble protective layer using a developer instead of etching required by previous methods. Conventional developer-soluble anti-reflective coatings and gap-fill materials can be used to form the protective layer. Custom layers with developer solubility can also be prepared. Microelectronic structures formed by the above processes are also disclosed.

  • Publication number: 20120006785
    Abstract: A low friction top coat over a multilayer metal/ceramic bondcoat provides a conductive substrate, such as a rotary tool, with wear resistance and corrosion resistance. The top coat further provides low friction and anti-stickiness as well as high compressive stress. The high compressive stress provided by the top coat protects against degradation of the tool due to abrasion and torsional and cyclic fatigue. Substrate temperature is strictly controlled during the coating process to preserve the bulk properties of the substrate and the coating. The described coating process is particularly useful when applied to shape memory alloys.
