Abstract
A method includes directing an acoustically agitated fluid stream at a first surface of a substrate to cause the substrate to vibrate mechanically thereby dislodging contaminant particles on the substrate. The first surface of the substrate is opposite a second surface of the substrate. The second surface of the substrate includes a pattern. An amplitude of the acoustically agitated fluid stream is configured to produce an acoustic response along an entirety of the second surface.
