摘要:
A system, apparatus and method for processing flat articles with acoustical energy. The inventive system, apparatus and method can remove particles from both sides of a wafer more efficiently and effectively. In one aspect, the invention is a system and/or method for processing flat articles wherein a liquid is applied to both major surfaces of the flat article. A first transducer assembly is positioned adjacent to a first of the major surfaces of the flat article and a second member is positioned adjacent to a second of the major surfaces. The first transducer assembly generates and transmits acoustical energy to the first major surface of the flat article while the second member either: (1) reflects the acoustical energy generated by the first transducer assembly back to the second major surface of the flat article; and/or (2) generates and transmits acoustical energy to the second major surface of the flat article.

A system, apparatus and method for processing this flat articles, such as semiconductor wafers, with acoustical energy. In a cleaning process, the inventive system, apparatus and method can remove particles from both sides of a wafer more efficiently and effectively. in one aspect, the invention is a system for processing flat articles comprising: a rotatable support for supporting a flat article; a first dispenser for applying liquid to a first surface of a flat article on the rotatable support; a second dispenser for applying liquid to a second surface of a flat article on the rotatable support; a first transducer assembly comprising a first transducer for generating acoustic energy and a first transmitter acoustically coupled to the first transducer, the first transducer assembly positioned so that when the first dispenser applies liquid to the first surface of a flat article on the rotatable support, a first meniscus of liquid is formed between a portion of the first transmitter and the first surface of the flat article; and a second transducer assembly comprising a second transducer for generating acoustic energy and a second transmitter acoustically coupled to the second transducer, the second transducer assembly positioned so that when the second dispenser applies liquid to the second surface of the flat article on the rotatable support, a second meniscus of liquid is formed between a portion of the second transmitter and the second surface of the flat article.
