    摘要: A method for removing impurities and deposits formed in a contact hole of a semiconductor device. The method comprises the step of bathing the semiconductor device in a solution having concentrations of between about 25 to 35 weight percent of Isopropyl Alcohol (IPA), 2 to 4 weight percent of H2O2, 0.05 to 0.25 weight percent of HF, and the remaining percent of deionized water. Such bathing is preferably carried out with the solution maintained at a constant temperature of between about 20 to 25° C. for about 1 to 5 minutes.

    摘要: A method for manufacturing semiconductor devices including removing a photoresist and cleaning the substrate after removing the photoresist. The method for manufacturing semiconductor devices comprises removing the photoresist remaining on a semiconductor substrate using a dry etching process. The substrate is subsequently cleaned using a cleaning composition comprising a mixture of 25 to 35 weight percent of Isopropyl Alcohol (IPA), 2.0 to 4.0 weight percent of hydrogen peroxide (H.sub.2 O.sub.2), 0.05 to 0.25 weight percent of hydrofluoric acid (HF), and the remaining weight percent of deionized water.
