Patents by Inventor Jung Kyu JO

Jung Kyu JO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11493845
    Abstract: An anti-reflective coating composition is provided. The anti-reflective coating composition of the present invention can be useful in preventing a pull-back phenomenon in which an anti-reflective coating layer tears on a corner of a pattern of a substrate during a heat curing process and improving gap-filling performance of the pattern since a crosslinker is attached to a polymer in the composition and the content of the low-molecular-weight crosslinker in the composition is minimized to regulate a heat curing initiation temperature.

  • Publication number: 20220267194
    Abstract: An etching device includes a chamber; a supporter disposed in the chamber; a heater disposed in the supporter; and an applier disposed on the supporter. A glass is disposed on the supporter, the applier applies an etchant on the glass such that a thickness of the etchant applied reduces from a center of the glass toward an edge of the glass.

  • Patent number: 11262656
    Abstract: Organic coating compositions, particularly antireflective coating compositions for use with an overcoated photoresist, are provided that comprise that a blend of two or more resins, where one resin has epoxy groups either pendant or fused to the polymer backbone. Preferred coating compositions include: 1) a first resin that comprises one or more epoxy reactive groups; and 2) a crosslinker resin that is distinct from the first resin and comprises epoxy groups.

  • Patent number: 9558987
    Abstract: Gap-fill methods comprise: (a) providing a semiconductor substrate having a relief image on a surface of the substrate, the relief image comprising a plurality of gaps to be filled; (b) applying a gap-fill composition over the relief image, wherein the gap-fill composition comprises a non-crosslinked crosslinkable polymer, an acid catalyst, a crosslinker and a solvent, wherein the crosslinkable polymer comprises a first unit of the following general formula (I): wherein: R1 is chosen from hydrogen, fluorine, C1-C3 alkyl and C1-C3 fluoroalkyl; and Ar1 is an optionally substituted aryl group that is free of crosslinkable groups; and a second unit of the following general formula (II): wherein: R3 is chosen from hydrogen, fluorine, C1-C3 alkyl and C1-C3 fluoroalkyl; and R4 is chosen from optionally substituted C1 to C12 linear, branched or cyclic alkyl, and optionally substituted C6 to C15 aryl, optionally containing heteroatoms, wherein at least one hydrogen atom is substituted with a functional group
