Abstract:
1. A method of cleaning at least one substrate comprising: (a) positioning a substrate in a process chamber having a gaseous environment with a first temperature and a first partial pressure for a first gas; (b) providing a transmitter so that at least a portion of the transmitter is in close proximity to and spaced from a surface of the substrate; (c) supplying a solution to the surface of the substrate so as to form a film of the solution on the surface of the substrate, the film being in contact with the portion of the transmitter the solution comprising a cleaning liquid and the first gas dissolved in the solution at a supersaturated concentration for the first temperature and the first partial pressure; and (d) applying acoustical energy via the transmitter through the film of the solution and to the substrate.
