  • Substrate floating apparatus and method of manufacturing liquid crystal display apparatus using the same
    Patent number: 7037063
    Abstract: There are provided a substrate floating apparatus for preventing interference between a glass substrate and a floating board when floating and conveying the glass substrate and a method of manufacturing LCD devices using the substrate floating apparatus. The substrate floating apparatus includes a body into which floating fluid is supplied and which stores the floating fluid, a floating board that is placed on the top of the body and through which the floating fluid is sprayed to float the substrate to the predetermined height, and a fixing member that mechanically fixes the floating board on the top of the body. A certain process is performed while floating the substrate.

  • Large-area mask and exposure system having the same
    Patent number: 6924880
    Abstract: Provided are a large-area mask and an exposure system having the same. The mask includes a transparent substrate, which includes a light transmission region and a light-blocking region, and a plurality of bars, which is arranged on the substrate to support the substrate. When the large-area mask is installed on the exposure system, the bars can support the mask, thus preventing downward level shifting of the mask.
