发明名称 Method and apparatus for cleaning a substrate
摘要 In a method and an apparatus for cleaning a substrate using a laser beam, an inner chamber is disposed in a process chamber to define a space in which a laser-induced shock wave is generated. The laser beam is focused on a laser focus positioned in the inner chamber, and thus the laser-induced plasma shock wave is generated around the laser focus. The plasma shock wave is reflected from inner surfaces of the inner chamber and is irradiated on the substrate through a lower portion of the inner chamber. As a result, the intensity of the plasma shock wave irradiated on the substrate is increased, and thus the contaminants on the substrate may be effectively removed.
