  • Patent number: 7146678
    Abstract: A system for removing dust, dirt and like from the surface of a flexible paper substrate and accurately positioning same comprises a transport assembly for conveying the paper substrate along a path of travel. The transport assembly includes a rotating vacuum drum having an outer surface over which the paper substrate is trained in the direction of drum rotation as it moves along the path of travel. Openings are provided in the outer surface of the vacuum drum, and a suction source is connected to those openings so that dust, dirt and the like on the surface of the paper substrate are drawn away by the suction as the paper substrate moves along the path of travel over the drum. The linear speed of the paper substrate is slightly more or less than the surface velocity of the vacuum drum so that the paper sweeps across the drum surface during the cleaning process.

  • Patent number: 7117878
    Abstract: Each immersed jet creates turbulences as a result of the resistance of the medium in which it is immersed and at the end of its effective range the complete introduced energy is broken down into turbulent flows. These turbulent flows observed as a whole are local, thus are small-scale. However, these small-scale turbulences which have a strong eroding effect. The present invention produces as high a number as possible of small-scale turbulences and distributes them over a large volume. Large volume is to be understood as, for example, 3000–4000 m3 on a surface of 2000 m2 and a height of 2 m as is the case with a storage tank of 50 m diameter and a liquid column of 3 m. The problem thus lies in the optimal distribution of the introduced or applied energy.

  • Patent number: 7112546
    Abstract: The present invention provides, in one embodiment, a method of manufacturing semiconductor devices. The method comprises transferring one or more substrate into a deposition chamber and depositing material layers on the substrate. The chamber has an interior surface. The method further includes, between the transfers, cleaning the deposition chamber using an in situ ramped cleaning process when material layer deposits in the deposition chamber reaches a predefined thickness. The in situ ramped cleaning process comprises forming a reactive plasma cleaning zone by dissociating a gaseous fluorocompound introduced into a deposition chamber in a presence of a plasma. The cleaning process further includes ramping a flow rate of the gaseous fluorocompound in a presence of the plasma to move the reactive plasma cleaning zone throughout the deposition chamber, thereby preventing a build-up of localized metal compound deposits on the interior surface.

  • Patent number: 7051741
    Abstract: A method of resist stripping for use during fabrication of semiconductor devices. A semiconductor substrate with a resist material formed thereon, such as a silicon wafer, is positioned in a sealed chamber in communication with a plasma-generating source. A gaseous material which includes a reducing agent is passed through the plasma-generating source to produce a plasma stream. The plasma stream is directed at the semiconductor substrate for a predetermined period of time to remove the resist material from the semiconductor substrate. A reducing environment is produced in the sealed chamber by the plasma stream, which can passivate and strip the resist material simultaneously.

  • Patent number: 7048805
    Abstract: A dual mode carpet cleaning method is capable of being used in both a deep cleaning mode and a fast drying surface cleaning mode. The method utilizes a carpet cleaning apparatus that provides selective communication with different sets of cleaning jets. One set of cleaning jets is operated to deliver a first cleaning solution that penetrates deeply into a carpet in the deep cleaning mode. A second set of cleaning jets is operated to deliver a lower flow rate of a second cleaning solution that does not penetrate as deeply into the carpet and dries quickly. The method involves manually operating a valve on the apparatus to selectively communicate a source of cleaning fluid of the apparatus with one of the first set of cleaning jets and the second set of cleaning jets, and discharging the cleaning liquid from the selected one of the first set of cleaning jets and second set of cleaning jets onto a carpet to be cleaned.
