Patent ID: 7518288

Claim:
A system for processing of an article comprising: a rotary support for supporting an article; a first conduit for applying fluid to a surface of the article positioned on the rotary support; a second conduit for applying fluid to an opposite surface of the article positioned on the rotary support; a transducer assembly comprising (i) a quartz or sapphire resonator positioned adjacent to the surface of the article on the rotary support so that when fluid is applied to the surface of the article via the first conduit, the resonator is fluidly coupled to the surface of the article and (ii) a transducer coupled to the resonator and adapted to generate acoustic energy that is transmitted through the resonator, into the fluid on the surface of the article, through the article, and into the fluid on the opposite surface of the article; and the transducer located within an enclosed space having at least one opening for flowing a gas into the enclosed space, the at least one opening opposing and aligned with a major surface of the transducer.
