  • Patent number: 8628698
    Abstract: Disclosed is a resin composition for a protective layer of a color filter including an acrylate-based resin including a repeating unit represented by each of Chemical Formulae 1 to 3, a melamine-based resin represented by Chemical Formula 4, a thermal acid generator (TAG), and a solvent.
    Type: Grant

  • Patent number: 8383737
    Abstract: A compound for filling small gaps in a semiconductor device and a composition comprising the compound are provided. The composition can completely fill holes having a diameter of 70 nm or less and an aspect ratio (i.e. height/diameter ratio) of 1 or more in a semiconductor substrate without any defects, e.g., air voids, by a general spin coating technique. In addition, the composition can be completely removed from holes at a controllable rate without leaving any residue by the treatment with a hydrofluoric acid solution after being cured by baking. Furthermore, the composition is highly stable during storage.

  • Patent number: 8299197
    Abstract: A polymer for gap-filling in a semiconductor device, the polymer being prepared by polycondensation of hydrolysates of the compound represented by Formula 1, the compound represented by Formula 2, and one or more compounds represented by Formulae 3 and 4: [RO]3Si—[CH2]n—Si[OR]3??(1) wherein n is from 0 to 2 and each R is independently a C1-C6 alkyl group; [RO]3Si—[CH2]nX??(2) wherein X is a C6-C12 aryl group, n is from 0 to 2, and R is a C1-C6 alkyl group; [RO]3Si—R???(3) wherein R and R? are independently a C1-C6 alkyl group; and [RO]3Si—H??(4) wherein R is a C1-C6 alkyl group.

  • 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.
