Abstract
A method for megasonic processing of an article. In one aspect, the invention may be a method of processing semiconductor wafers comprising: supporting the semiconductor wafer substantially horizontally; positioning a rod-like probe above an upper surface of the semiconductor wafer in an orientation other than normal to the upper surface of the substrate; applying a fluid to the upper surface of the semiconductor wafer so that a film of the fluid is formed between at least a portion of the rod-like probe and the upper surface of the semiconductor wafer; and vibrating the rod-like probe to transmit energy to the upper surface of the semiconductor wafer via the film of the fluid to loosen particles on the upper surface of the semiconductor wafer.
