Publication number: 20130206164Abstract: In a piezoelectric device, a first electrode and a second electrode are disposed to be opposed to each other on plate surfaces of the piezoelectric device, a first electrode plane of the piezoelectric device is fixedly bonded to a plate surface of a vibrating plate, a piezoelectric material forming the piezoelectric device is polarized in a direction parallel to the first electrode plane, the piezoelectric device is fixed to a base through a second electrode plane of the piezoelectric device, and the piezoelectric device generates a thickness-shear vibration with the fixed second electrode plane being a reference plane. The piezoelectric vibration generated by the piezoelectric device generates a flexural vibration in the vibrating plate, to thereby remove dust adhering to a surface of the vibrating plate.Type: ApplicationFiled: March 14, 2013Publication date: August 15, 2013Applicant: CANON KABUSHIKI KAISHAInventor: CANON KABUSHIKI KAISHA

Publication number: 20130206163Abstract: A system for ultrasonically cleaning one or more wires of a wire saw for slicing semiconductor or solar material into wafers. The system includes an ultrasonic transducer connected to a sonotrode. The system also includes a sonotrode plate adjacent to one or more of the wires. The sonotrode plate has an opening that exposes the sonotrode to one or more of the wires. The system further includes a tank for delivering a flow of liquid to contact the sonotrode and one or more of the wires. The tank is positioned on the same side of the wires as the sonotrode plate. The ultrasonic transducer is configured to vibrate and form cavitations in the liquid for the removal of contaminants from a surface of one or more of the wires.Type: ApplicationFiled: August 14, 2012Publication date: August 15, 2013Applicant: MEMC Electronic Materials, SPAInventors: Carlo Zavattari, Ferdinando Severico, Roland R.

Publication number: 20130192629Abstract: A substrate cleaning chamber includes a contoured ceiling electrode having an arcuate surface that faces a substrate support and has a variable cross-sectional thickness to vary the gap size between the arcuate surface and the substrate support to provide a varying plasma density across the substrate support. A dielectric ring for the cleaning chamber comprises a base, a ridge, and a radially inward ledge that covers the peripheral lip of the substrate support. A base shield comprises a circular disc having at least one perimeter wall. Cleaning and conditioning processes for the cleaning chamber are also described.Type: ApplicationFiled: January 11, 2013Publication date: August 1, 2013Inventors: Vineet Mehta, Karl M. BROWN, John A. Pipitone, Daniel J. Hoffman, Steven C. Shannon, Keith A. Miller, Vijay D. PARKHE
