  • Patent number: 8304034
    Abstract: The present invention relates to one-solution type thermosetting resin composition for a protective film of a color filter, and a color filter including the same. The one-solution type thermosetting resin composition includes a copolymer (A) including (meth)acrylate with an epoxy cyclic structure at the side chain, (meth)acrylate with a hydroxyl terminal, acid anhydride, and maleimide with a substituent; an epoxy resin (B); a base-generating agent (C); and an organic solvent (D). When a protective film of a color filter is prepared by using the one-solution type thermosetting resin composition according to the present invention, it has excellent storage stability as well as excellent flatness, close-contacting property, transmission properties, heat resistance, and chemical resistance.

  • Patent number: 7947795
    Abstract: A polymer for filling gaps in a semiconductor substrate and a composition using the polymer are provided. According to the composition, holes having a diameter of 100 nm or less and an aspect ratio (i.e. a ratio between the diameter and height of the holes) of 1 or higher in semiconductor substrates can be substantially completely filled by common spin coating without formation of defects, e.g., air voids, the film can be dissolved by an aqueous alkaline solution (i.e. a developing solution) until a desired thickness is reached, the film is highly resistant to isopropyl alcohol (IPA) and plasma etching after curing by baking, and residue can be rapidly removed from the inside of the holes by ashing.

  • Patent number: 7722932
    Abstract: Provided herein are one-solution type thermosetting resin compositions that may be useful to form protective films for color filters used in liquid crystal displays or image sensors. According to some embodiments, the resin compositions may include a self-curable copolymer and an epoxy compound. The protective films may exhibit desirable flatness, adhesiveness, transmittance, heat resistance and chemical resistance. Also provided are methods of forming a film on a substrate, and substrates having a film formed thereon. In addition, provided herein are color filters including a film formed from a composition according to an embodiment of the invention, and liquid crystal displays and image sensors including such color filters.
