  • Patent number: 11926807
    Abstract: A cleaning composition for removing post-etch or post-ash residues from a semiconductor substrate, and a cleaning method using the same are disclosed. The cleaning composition can comprise water; a fluorine compound; an alkanolamine compound; and a corrosion inhibitor. The corrosion inhibitor is a mixture of a first corrosion inhibitor and a second corrosion inhibitor. When using the cleaning composition, it is possible to efficiently remove the residues of various aspects existing on a surface of the substrate or the semiconductor device without damage to a substrate or a semiconductor device including various metal layers, insulating layers, etc. Accordingly, when a highly integrated and miniaturized semiconductor device is manufactured, it may be advantageously applied to the removal of residues generated on the surface of the substrate or the semiconductor device.
    Type: Grant
