  • Patent number: 11968824
    Abstract: A semiconductor device includes a bit line structure, first and second capping patterns, first and second contact plug structures, and a capacitor. The bit line structure extends on a cell region and a dummy region. The first capping pattern is adjacent the bit line structure on the cell region. The second capping pattern is adjacent the bit line structure on the dummy region. The first contact plug structure is adjacent the bit line structure and the first capping pattern on the cell region, and includes a lower contact plug and a first upper contact plug sequentially stacked. The second contact plug structure is adjacent the bit line structure and the second capping pattern on the dummy region, and includes a dummy lower contact plug and a second upper contact plug sequentially stacked. The capacitor contacts an upper surface of the first contact plug structure on the cell region.

  • Patent number: 11922607
    Abstract: Disclosed is an electronic device including a memory and a processor electrically connected with the memory. The memory stores instructions that, when executed, cause the processor to control the electronic device to: obtain information about a maximum value of brightness of image content based on metadata of the image content, to perform tone mapping on at least one or more frames corresponding to a preview image of the image content based on the information about the maximum value of the brightness, and to output the preview image based on the at least one or more frames on which the tone mapping is performed, on a display device.

  • Patent number: 7135133
    Abstract: The present invention relates to a method and apparatus for manufacturing plastic optical transmission medium. The subject method and apparatus can produce a variety of optical transmission medium, including for example, graded refractive index polymer optical fiber, graded refractive index rod lens, and step index polymer optical fiber. The subject optical transmission medium have improved characteristics and efficiency, due, at least in part, to better control of the profile of the refractive index distribution and stable high temperature operation of the medium. High efficiency of manufacturing can be achieved by the subject method and apparatus which can permit continuous extrusion at high speed.

  • Publication number: 20050226574
    Abstract: This invention concerns a method and apparatus for manufacturing a sheet and a two-dimensional matrix of plastic optical fibers. The fibers may be of the step-index or graded-index type. Co-extrusion through a specially designed die is used to produce a sheet composed of a fiber array. The fiber sheet (ribbon) can be used for transmitting optical signals. These arrays may also be stacked and fused at high temperatures to form the two-dimensional matrix required for many applications such as large area image transfer. In addition, a high-speed, continuous manufacturing method is disclosed to produce a massive two-dimensional matrix of fibers. The method of manufacture permits high quality image transfer at low manufacturing cost in a wide array of geometries.
