    摘要: A slurry composition includes about 4.25 to about 18.5 weight percent of an abrasive, about 80 to about 95 weight percent of deionized water, and about 0.05 to about 1.5 weight percent of an additive. The slurry composition may further include a surfactant. In a polishing method using the slurry composition, a polysilicon layer may be rapidly polished, and also dishing and erosion of the polysilicon layer may be suppressed.

    摘要: Disclosed is an organic stripping composition and a method of etching a semiconductor device in which the generation of an Si pitting phenomenon can be prevented. The composition includes a compound including a hydroxyl ion (OH−), a compound including a fluorine ion (F−) and a sufficient amount of an oxidizing agent to control the pH of the composition within the range of from about 6.5 to about 8.0. The method includes dry etching an oxide by a dry etching using a plasma, and then ashing the etched oxide using an ashing process to remove an organic material. The method further includes supplying the organic stripping composition to remove residues including any residual organic material, a metal polymer, and an oxide type polymer. The stripping composition is stable onto various metals and does not induce the Si pitting phenomenon.
