  • SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD
    Publication number: 20230215693
    Abstract: The inventive concept provides a substrate processing apparatus. The substrate processing apparatus may include a chamber having an interior space, a support unit that supports a substrate in the interior space, a ring unit disposed on an edge region of the support unit when viewed from above, an impedance control unit electrically connected to the ring unit to control a flow or density of plasma in an edge region of the substrate and a filter unit disposed between the ring unit and the impedance control unit.

  • PHOTOSENSITIVE RESIN COMPOSITION AND COLOR FILTER USING SAME
    Publication number: 20170160635
    Abstract: The present application relates to a photosensitive resin composition and a color filter using the same. If the photosensitive resin composition provided in the present application is used, since a color deeper than that of the related art can be implemented, in various thickness ranges of a color filter, color reproducibility may be increased and a contrast ratio may be increased.

  • Photosensitive resin composition
    Patent number: 8399176
    Abstract: Disclosed is a photosensitive resin composition suitable for use in a transflective liquid crystal display (LCD). The photosensitive resin composition uses, as an alkali-soluble binder resin, a blend of two kinds of binder resins. The first binder resin has a weight average molecular weight greater than or equal to 1,000 but lower than 20,000 and contains no reactive group. The second binder resin has a weight average molecular weight greater than or equal to 20,000 but lower than 80,000 and contains reactive groups. The photosensitive resin composition has good adhesion to an underlying substrate while forming a high resolution fine pattern.
