Patent ID: 7231682

Claim:
A system for cleaning a semiconductor substrate, comprising: a chamber configured to support the semiconductor substrate, the chamber including, an acoustic energy cleaning tool configured to be applied to a feature side of the semiconductor substrate, the acoustic energy cleaning tool having a first annular inlet for delivering a first fluid to the feature side surface, a second annular inlet defined around the first annular inlet for delivering a second fluid to the feature side surface and an annular outlet defined between the first annular inlet and the second annular inlet, the annular outlet configured to remove the first fluid and the second fluid, thereby causing a meniscus to form over a source of acoustic energy disposed within the feature side cleaning tool; a brush cleaning tool configured to be applied to a non-feature side of the semiconductor substrate while the feature side is being cleaned; and a fluid delivery system capable of applying a feature side fluid to the feature side and a non-feature side fluid to the non-feature side.
