Abstract:
1. A method of processing a substrate comprising: a) supporting a substrate having a surface; b) rotating the substrate about a rotational axis; c) flowing a liquid from a liquid source through a first sonic energy source to apply a first some energy having a first power level to the liquid, thereby convening the liquid into a sonic treated liquid; d) positioning a vibration transmitter so that at least a portion of the vibration transmitter is adjacent the surface of the substrate, the vibration transmitter acoustically coupled to a second sonic energy source; e) applying the sonic-treated liquid to the surface of the substrate so as to form a film of the sonic-treated liquid on the surface of the substrate that couples the portion of the transmitter to the surface of the substrate; and f) applying second sonic energy, generated by the second sonic energy source and having a second power level, from the vibration transmitter through the sonic-treated liquid and to the surface of the substrate; wherein the first power level is greater than the second power level; and wherein the first sonic energy does not contact the surface of the substrate.
