  • Patent number: 6783919
    Abstract: The invention relates to a TFT-LCD high-performance stripper composition for a photoresist, and more particularly to a stripper composition for a photoresist comprising: 20-60 wt % of monoethanolamine, 15-50 wt % of N,N-dimethylacetamide, 15-50 wt % of carbitol, and 0.1-10 wt % of gallic acid. The invention also provides a stripper composition for a photoresist comprising: 20-60 wt % of monoethanolamine, 15-50 wt % of N,N-dimethylacetamide, and 15-50 wt % of carbitol. The stripper composition for a photoresist of the invention significantly reduces stripping time when applied to the TFT-LCD manufacturing process and leaves no impurity particles. By allowing the hard baking and ashing processes to be omitted, the gate process line can be simplified, which enables cost reduction. In addition, when it is applied to a process wherein silver (Ag) is used as reflective/transflective layer, it offers stripping ability and corrosion resistance of the pure Ag layer.

    Abstract: Methods and solutions for cleaning a polished aluminum-containing layer, and the structures formed by these methods. The method for cleaning the polished aluminum-containing layer is practiced by contacting a polished aluminum-containing layer with a solution comprising water and a corrosion-inhibiting agent. In these methods and solutions, the water may be deionized water, the corrosion-inhibiting agent may be citric acid or one of its salts, and the solution may contain additional additives, such as chelating agents, buffers, oxidants, antioxidants, and surfactants. These methods and solutions reduce the corrosion caused by DI water used in cleaning polished aluminum-containing layers and maintain a passivative environment which protects the exposed aluminum structures.

The compositions contain from about 1% to about 60% of an amine oxide detergent surfactant, an aqueous carrier liquid, and an acidifying agent having a pK.sub.a of less than about 6.0. The compositions contain enough of the acidifying agent to protonate at least about 10% of the amine oxide species within the compositions and to provide a composition pH of between about 3 and 7. These no-rinse liquid hard surface cleaning compositions have excellent cleaning properties, they do not leave a visible residue when they dry, and they cause minimal or no staining of vinyl surfaces. Also disclosed are a method for cleaning vinyl surfaces using the liquid compositions, and non-liquid compositions from which the mildly acidic liquid compositions can easily be obtained by adding an aqueous liquid.
