Abstract

A substrate cleaning apparatus is provided. The apparatus includes a transducer capable of resonating at a high frequency and a brush material attached to a surface of the transducer. The brush material includes at least one passage extending to the surface of the transducer and is configured to be applied to a surface of a substrate. When the transducer resonates at the high frequency, the transducer is capable of imparting acoustic energy to the surface of the substrate at a location of the at least one passage.
