Abstract
A transducer assembly used for the megasonic processing of an article. In one aspect, the transducer assembly comprises: a vibration transmitter having a rear portion adapted to be supported adjacent to an article to be processed and having an elongated forward portion adapted to extend close to a surface of the article so that when a fluid is applied to the surface of the article, a meniscus of the fluid is formed between the elongated forward portion and the surface of the article; and a transducer coupled to the rear portion of the transmitter, the transducer adapted to oscillate at a frequency for propagating megasonic energy through the elongated forward portion of the transmitter and into the meniscus of the fluid. In one embodiment, the transducer assembly can further comprise a housing with at least one opening for flowing a gas into a space in the housing in contact with the transducer.
