Patent ID: 7040330

Claim:
A system for cleaning a single semiconductor substrate, comprising: a tank having an inner cavity defined by a base and at least one sidewall extending therefrom, the tank configured to retain a volume of a liquid within the inner cavity to immerse the single semiconductor substrate; a substrate support configured to support and rotate the single semiconductor substrate about an axis of the semiconductor substrate, the substrate support further configured to support and rotate the single semiconductor substrate in the inner cavity of the tank wherein the substrate support orients a surface of the semiconductor substrate to be substantially parallel to the base a first megasonic transducer coupled to the base with a top surface of the megasonic transducer, wherein the top surface of the megasonic transducer being substantially parallel to a bottom surface of the single semiconductor substrate; and a second megasonic transducer coupled to the at least one sidewall, wherein the first megasonic transducer is configured to generate acoustic energy associated with a direction substantially perpendicular to the bottom surface of the single semiconductor substrate and the second megasonic transducer is configured to generate acoustic energy associated with a direction substantially parallel to the bottom surface of the single semiconductor substrate.
