Patents by Inventor Sang Geun Yun

Sang Geun Yun 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: 8642437
    Abstract: A composition with improved shelf life for filling small gaps in a semiconductor device is provided. The composition comprises an end-capped silicone polymer. The molecular weight of the end-capped silicone polymer is not varied during storage. In addition, the dissolution rate (DR) of the composition in an alkaline developing solution is maintained at a desired level during storage. That is, the composition is highly stable during storage. Therefore, the composition is suitable for use in a node separation process for the fabrication of a semiconductor capacitor.
    Type: Grant

  • Patent number: 8188576
    Abstract: A compound for filling small gaps in a semiconductor device, a composition for filling small gaps in a semiconductor device, and a method of fabricating a semiconductor capacitor, the compound including hydrolysates prepared by hydrolysis, in the presence of an acid catalyst, of compounds represented by Formulae 1, 2, and 3: [RO]3Si—[CH2]nR???(1) wherein, in Formula 1, n is an integer from 0 to about 10, and R and R? are each independently a hydrogen atom, a C1-C12 alkyl group, or a C6-C20 aryl group; HOOC[CH2]nR2Si—O—SiR?2[CH2]nCOOH??(2) wherein, in Formula 2, each n is independently an integer from 0 to about 10, and R and R? are each independently a C1-C12 alkyl group or a C6-C20 aryl group; and R3Si—O—X??(3) wherein, in Formula 3, X is R? or SiR?3, and R and R? are each independently a C1-C12 alkyl group or a C6-C20 aryl group, or a polycondensate prepared by polycondensation of the hydrolysates represented by Formulae 1, 2, and 3.
