  • Publication number: 20110155691
    Abstract: The present invention provides a manufacturing method of a magnetic recording medium capable of reducing the deterioration of a recording layer and improving the Duty cycle of the recording layer. An embodiment of the present invention is a manufacturing method of a patterned recording medium such as BPM (Bit Patterned Media) and DTM (Discrete Track Media). The manufacturing method has a deposition step of depositing a resist protective film on a resist pattern formed on a workpiece containing a recording layer, and a recording layer processing step of processing the recording layer into a pattern shape by dry etching using the resist pattern and the resist protective film as a mask.

  • Publication number: 20100064373
    Abstract: A method for using a location-based service while preserving anonymity includes receiving a location associated with a mobile node, receiving an anonymity level associated with the mobile node, computing a region containing the location of the mobile node and a number of footprints based on the anonymity level, wherein each of the footprints from a different user, and providing the region to a location-based service to thereby preserve anonymity of the mobile node. A method also allow a mobile device or its user to specify the anonymity level by selecting a public region consistent with a user's feelings towards desired privacy.

  • Patent number: 7067436
    Abstract: In a method of forming a silicon oxide film, the silicon oxide film is formed on a substrate by the use of a plasma CVD method. A plasma-generating region is separated from a deposition region which includes excitation oxygen molecules and excitation oxygen atoms. Plasma of first gas containing oxygen atoms is formed in the plasma-generating region while second gas containing silicon atoms is supplied into the deposition region. First quantity of the excitation oxygen molecules and second quantity of the excitation oxygen atoms are controlled intentionally.

  • Patent number: 6892669
    Abstract: A CVD apparatus produces plasma to generate radicals and uses the radicals, silane, and the like so as to deposit films on substrates in a vacuum vessel 12. The vacuum vessel has a partitioning wall section 14 for separating the inside thereof into a plasma-generating space 15 and a film deposition process space 16. The partitioning wall section has a plurality of through-holes 25 and diffusion holes 26. An interior space 24 receives the silane or the like fed into the film deposition process space through diffusion holes 16. The radicals produced in the plasma-generating space are fed into the plasma-generating space through the through-holes. The through-holes satisfy the condition of uL/D>1, where u represents the gas flow velocity in the through-holes, L represents the effective length of the through-holes, and D represents the inter-diffusion coefficient.
