  • Patent number: 6908892
    Abstract: The present invention is a photoresist remover composition used in order to remove photoresist during the manufacturing process of semiconductor devices, such as large-scale integrated circuits and very large-scale integrated circuits. The present invention comprises 2˜20 weight % of water-soluble hydroxylamine, 5˜15 weight % of oxime compound containing 2 or 3 hydroxyl groups, and 30˜55 weight % of alkyl amide. The photoresist remover composition according to the present invention can easily and quickly remove a photoresist layer that is cured by the processes of hard-bake, dry-etching, and ashing and a side-wall photoresist polymer that is produced from the lower metal film by the reaction of the photoresist with etching and ashing gases during these processes. Especially, the photoresist remover composition has a good property of removing the side-wall photoresist polymer produced from the layers of aluminum, aluminum alloy, and titanium nitride.

    Abstract: Fabric softener compositions comprising certain red colorants that exhibit excellent deep, dark red colorations (for aesthetic purposes) and mix very well with other colorants to provide differing red shades and tints therein, which simultaneously exhibit very low, if any staining capabilities on fabrics treated therewith, are provided. Such deep and dark red colorations have heretofore been unavailable within fabric softener formulations due to the tendency of such prior colorants to exhibit unacceptable staining levels, particularly when formulated at similar deep and dark shades as now provided within the inventive low-staining formulations. Apparently, and quite unexpectedly, the colorants present therein react favorably with quaternary ammonium salt softening agents in a manner to prevent reaction with the fibers of the treated fabrics themselves, thereby preventing staining thereon and therein.
