  • Patent number: 6579668
    Abstract: A photoresist remover composition including: 10 to 30% by weight amine compound; 20 to 60% by weight glycol series solvent; 20 to 60% by weight polar solvent; and 0.01 to 3% by weight perfluoroalkylethyleneoxide. The performance of the photoresist remover composition in stripping the photoresist residue, which is generated by dry or wet etching, ashing or ion implantation, from a substrate is enhance, and the photoresist remover composition is able to be smoothly applied over a variety of metal layers including an aluminum (Al) layer. Also, the photoresist remover composition corrodes the metal layers very little.

  • Patent number: 6183942
    Abstract: The present invention relates to a thinner composition for removing a spin-on-glass coating and a photoresist which are used in the semiconductor components manufacturing process. The present invention provides a mixed thinner composition which is mixed propylene glycol monoalkyl ether with monooxycarbonic acid ester, alkyl ethanoate, and alkyl lactate in a thinner composition for cleaning and photoresist removal applications in the semiconductor components manufacturing process. A thinner composition according to the present invention has the beneficial effects that the production yield can be improved during semiconductor component manufacturing since when the thinner composition is applied after the spin coating process, the undesired coating of the edge or the backside of the substrate can be removed promptly, completely, and effectively, and residual materials adhering to the surface of a substrate which must be reuse can be completely removed so that the substrate can be economically used.
