  • Patent number: 7867337
    Abstract: A substrate having a liquid film formed by pre-processing unit is transported by a substrate transport robot from the pre-processing unit to a freeze processing unit disposed away from the pre-processing unit. In the freeze-processing unit, the liquid film is frozen. This causes the adhesion power of contaminants adhering to the surface of the substrate reduce, and therefore the contaminants is detached from the surface of the substrate. Subsequently, the substrate which was subjected to the freezing process, is transported from the freeze processing unit to a post-processing unit which is disposed away from the pre-processing unit and the freeze processing. In the post-processing unit, a cleaning liquid is supplied to the frozen film on the rotating substrate, thereby easily removing the contaminants adhering to the substrate together with the frozen film.

  • Patent number: 6406552
    Abstract: A method for the cleaning of SiO2 grain is known whereby SiO2 grain comprising contaminations is heated to a temperature at which the contaminations soften or form melting agglomerates with the SiO2 grain, thus separating the contaminations and the SiO2 grain. On this basis and to specify a method which achieves high grain purity at comparatively little expenditure of time, material and costs, and to provide a simple device suitable for the implementation of the method, it is proposed according to the invention that the SiO2 grain is fed to and heated in a gas stream which is directed towards an impingement plate, the SiO2 grain being accelerated in the direction of the impingement plate such that softened contaminations or melting agglomerates adhere to the impingement plate and cleaned SiO2 grain is removed from the impingement plate.

  • Patent number: 6348102
    Abstract: Apparatus including an elongate pipe (1) for use in the transfer of fluids susceptible to form deposits on cooling such as wax deposits in oil, and a container (12) having a reusable heat source including a supercooled solution, e.g., of aqueous sodium acetate. The container (12) is in heat conducting contact with a surface of the pipe (1), preferably on at least one surface of the container. The deposit may be removed from inside the pipe (1) by locating in heat conducting relation to the pipe a reusable heat source including a supercooled solution, and activating crystallization in the solution liberating heat which causes at least some of the deposit to melt and/or dissolve.

  • Publication number: 20010050091
    Abstract: Cleaning a media surface, such as a disc surface, comprises subjecting the surface to a detector for sensing the nature of the surface for an irregularity in the smoothness of the surface. Directing, on detecting an irregularity beyond a predetermined amount, a burnishing pulse laser output to that irregularity, and energizing the laser to thereby impart an energy source to reduce the irregularity to a degree less than a predetermined amount.

  • Patent number: 6296717
    Abstract: An in-situ method for regenerating a chemical-mechanical polishing pad which includes the steps of: forming the polishing pad by dispensing liquid moldable material, such as wax, polymers or water, on a polishing surface and solidifying the liquid material by reducing the temperature, allowing the moldable material to harden; distributing slurry material on the polishing pad; polishing the surface of a semiconductor wafer with a combination of the slurry material and the polishing pad; and regenerating in-situ the polishing pad. This method quickly, easily and repeatably, resurfaces and refreshes the surface on which the a semiconductor wafer is polished. The polishing pad may also include abrasives embedded therein to enhance its polishing capabilities.

  • Patent number: 5935366
    Abstract: A process for preparing two connected powder transfer conduits for cleaning without releasing powder from the conduits. The conduits are connected to each other by flexible tube of a water-dissolvable material to enable powder communication between the two conduits. A sealing operation is performed to form a seal in the tube sufficient to prevent the powder communication from one side of the seal to the other. The seal is then severed to produce two tube sections where each tube section is sealed at the point of severance. A cleaning conduit is then place over at least one of the two tube sections and connected to the respective conduit. The cleaning conduit is connected to a liquid cleaning source which is adapted to deliver a cleaning liquid capable of dissolving the tube section thereunder upon contact therewith.
