  • Publication number: 20090312216
    Abstract: The present invention relates to a photoresist stripper composition for removing the photoresist in the manufacturing process of the semiconductor device. More particularly, the photoresist stripper composition comprises 3-20 wt % of hydrazine hydrate or amine compound; 20˜40 wt % of polar solvent; 0.01-3 wt % of corrosion inhibitor selected from the group consisting of imidazoline derivative, sulfide derivative, sulfoxide derivative, aromatic compound or aromatic compound with hydroxyl group; 0.01-5 wt % of monoalcohol compound of C2-C10; and 40-70 wt % of deionized water. The photoresist stripper composition for manufacturing the semiconductor can remove the photoresist film thermoset by hard bake, dry etching, ashing or ion implantation and denatured by the metallic by-product etched from the bottom metallic film in said process at low temperature easily and quickly, and minimize the corrosion of the bottom metallic wiring in the removing process of the photoresist.

  • Publication number: 20060014391
    Abstract: A metal-containing pattern structure is formed on a semiconductor substrate, and a cleaning composition is applied to the semiconductor substrate. The cleaning composition includes, based on a total weight of the cleaning composition, about 78 wt % to about 99.98 wt % of an acidic aqueous solution, about 0.01 wt % to about 11 wt % of a first chelating agent, and about 0.01 wt % to about 11 wt % of a second chelating agent. The metal-containing pattern structure includes an exposed first surface portion and a second surface portion covered with a polymer. Application of the cleaning solution forms a first corrosion-inhibition layer on the first surface portion of the metal-containing pattern structure, and removes the polymer from the second surface portion of the metal-containing pattern structure.
