Patent number: 8784567Abstract: A rapid and effective means for decontaminating fouled oil-control booms is provided. The process involves washing the boom with pressured washing fluid, reorienting the boom to facilitate full inspection, and drying the boom. This can be performed in an assembly-line manner, using one or more conveyors to transport the boom sequentially to a washing area, an inspection area, and a drying area. Consequently, contaminated oil-control booms can be cleaned and redeployed rapidly and inexpensively during an oil release accident.Type: GrantFiled: May 30, 2013Date of Patent: July 22, 2014Inventor: William G. Yates, Jr.

Patent number: 8764905Abstract: A method and system for cleaning lithography components including contacting a substrate having residue including organic compounds and graphitic carbon deposited on a surface thereof with hydrogen peroxide vapor. The hydrogen peroxide vapor is irradiated with electromagnetic radiation having a wavelength in the range of 100 nm to 350 nm forming hydroxyl radicals. The hydroxyl radicals react with the residue to remove the residue from the surface of the substrate.Type: GrantFiled: March 14, 2013Date of Patent: July 1, 2014Assignee: Intel CorporationInventors: Paul A. Zimmerman, Christof G. Krautschik

Patent number: 8764906Abstract: A method and cleaning solution for cleaning electronic substrates, such as a semiconductor wafers, hard disks, photomasks or imprint molds. The method comprises the steps of contacting a surface of the substrate with a cleaning solution comprised of a polyphosphate, and then removing the cleaning solution from the surface. Additional optional steps include applying acoustic energy to the cleaning solution while the cleaning solution is in contact with the surface, and removing the cleaning solution from the surface by rinsing the surface with a rinsing solution with or without the application of acoustic energy. The cleaning solution comprises a polyphosphate, such as any of the water soluble polyphosphates. Depending on the application, the cleaning solution may also comprise a base and/or a quantity of suspended particles. Complexing agents, amines, biocides, surfactants and/or other substances, may also be added to the cleaning solution.Type: GrantFiled: December 24, 2012Date of Patent: July 1, 2014Assignee: Fontana TechnologyInventor: Mark Jonathan Beck
