    摘要: A megasonic cleaning method and a megasonic cleaning apparatus are provided. Microcavitation bubbles may be formed by applying an electromotive force to a cleaning solution using a megasonic energy in a separate room from an object to be cleaned. The microcavitation bubbles having a stable oscillation among the formed microcavitation bubbles may be moved to the object to be cleaned. A surface of the object to be cleaned may be cleaned using the microcavitation bubbles having the stable oscillation. Particles attached onto the surface of the object to be cleaned may be effectively removed while preventing pattern damage.

    摘要: A cleaning method for a semiconductor substrate including placing the semiconductor substrate into a cleaning chamber and injecting ozone gas (O3) into the cleaning chamber. This process operates to cleanse the semiconductor substrate without corrosion or etching of the semiconductor substrate; even when the substrate has metal layer made of tungsten.
