Abstract:
A method of cleaning surfaces of substrates, comprising the steps of:submerging at least a portion of at least one substrate to be cleaned in a bath of cleaning fluid in a first chamber;bringing the submerged portion of said substrate into frictional contact with a brush;moving said brush relative to said substrate;generating a beam of ultrasonic energy along a predetermined direction beneath the surface of the bath of cleaning fluid substantially parallel to the substrate to be cleaned;removing the submerged portion of said substrate from the bath of cleaning fluid in the first chamber to a second chamber;inhibiting interaction of the atmospheres of the first and the second chamber;applying rinse fluid to the surface of the substrate; andapplying a solvent to the surface of the substrate, wherein said solvent induces a lowering of the surface tension of any fluid on the surface of said substrate.
