Abstract:
A method of cleaning and drying a generally flat substrate positioned on a rotatable support comprising the steps of:positioning a transmitter closely spaced above an upper surface of the substrate; applying fluid to the substrate to create a meniscus between the transmitter and the rotating substrate; applying megasonic energy to the transmitter to cause it to propagate megasonic energy through the meniscus to the substrate to loosen particles on the substrate while the substrate is rotating at a first rate; retracting the transmitter; and moving a substrate drying assembly support arm of a substrate drying assembly into position closely spaced above the substrate, the substrate drying assembly including an outlet for applying liquid to the upper surface of the substrate and including an outlet for applying a drying vapor to the upper surface of the substrate; wherein the substrate drying assembly support arm is moved into place as the transmitter is being retracted.
