Abstract

A system for megasonic processing of an article. In one aspect, the system for megasonic processing comprises a rotary support for supporting an article, a dispenser for applying a fluid to a surface of an article positioned on the rotary support; and a transducer assembly. The transducer assembly comprises (i) a transmitter positioned adjacent to the article on the rotary support so that when the fluid is applied to the surface of the article via the dispenser, a meniscus of the fluid is formed between a portion of the transmitter and the surface of the article and (ii) not more than one transducer coupled to the transmitter, the transducer adapted to oscillate at a frequency for propagating megasonic energy through the transmitter and into the meniscus of the fluid.

Claims (4)

1 . A system for megasonic processing of an article comprising:

a rotary support for supporting an article;

a dispenser for applying a fluid to a surface of an article positioned on the rotary support; and

a transducer assembly comprising (i) a transmitter positioned adjacent to the article on the rotary support so that when the fluid is applied to the surface of the article via the dispenser, a meniscus of the fluid is formed between a portion of the transmitter and the surface of the article and (ii) not more than one transducer coupled to the transmitter, the transducer adapted to oscillate at a frequency for propagating megasonic energy through the transmitter and into the meniscus of the fluid.
