  • Patent number: 10191385
    Abstract: An super-resolution system for nano-patterning is disclosed, comprising an exposure head that enables a super-resolution patterning exposures. The super-resolution exposures are carried out using electromagnetic radiation directed onto a medium using plasmonic structures, and in particular using plasmonic structures using specially designed super-resolution apertures, of which the “bow-tie” and “C-aperture” are examples. These specially designed apertures create small but bright images in the near-field transmission pattern. A printing head comprising an array of these apertures is held in close proximity to a medium for patterning. In some embodiments, a data processing system is provided to re-interpret the data to be patterned into a set of modulation signals used to drive the multiple individual channels and multiple exposures.

    Abstract: When an oxide semiconductor is deposited by a sputtering method, there is a difference in composition between a sputtering target and a film deposited using the sputtering target in some cases depending on a material of the oxide semiconductor. In manufacturing a sputtering target containing zinc oxide, a crystal which contains zinc oxide is formed in advance, the crystal is crushed, and then a predetermined amount of zinc oxide is added and mixed. After that, the resulting object is sintered to form the sputtering target. The composition of the sputtering target is adjusted by setting the proportion of zinc in the sputtering target higher than that of zinc in a film having a desired composition which is obtained at last, in consideration of the amount of zinc which is reduced at the time of deposition by a sputtering method, the amount of zinc which is reduced at the time of sintering, and the like.

  • Publication number: 20140160914
    Abstract: An information device is an information device that records information on or reproduces information from an information recording medium (3). The information device includes a light source (14) and a near-field light generating element (9) including a resonating section (22) configured such that plasmon resonance occurs between the resonating section (22) and a recording region (4). The resonating section (22) causes the plasmon resonance when emission light from the light source is irradiated on the near-field light generating element (9). A resonance enhancing film enhances the plasmon resonance between the resonating section (22) and the recording region (4). The resonating section (22) generates near-field light and irradiates the near-field light on the recording region (4) from a recording layer side.
