  • Patent number: 9669982
    Abstract: A method of packaging a CMP brush having a cylindrical brush portion and a pair of end connection portions. The method includes saturating the brush with a liquid; covering the cylindrical brush portion with a flexible sheet that extends around and engages the surface of the cylindrical portion; engaging each of the end connection portions with a respective end support; inserting the dampened brush into a rigid polymer tubular shipping container and supporting the end connection portions within the polymer tube; and providing an additional exterior self-supporting packaging.

  • Patent number: 8172923
    Abstract: An apparatus and method for maintaining low gas velocity variation across a diffuser membrane during the vent-up of a vacuum chamber is disclosed. The diffuser membrane permeability and the pressure conditions across the membrane are chosen to minimize variation in gas flow velocity through the membrane during the vent-up cycle. This reduces re-distribution of particles from a vacuum chamber onto sensitive substrates in the vacuum chamber during vent-up from sub-atmospheric pressure to atmospheric pressure.

  • Patent number: 7967882
    Abstract: Embodiments of the present invention provide low-profile surface mount filters. One embodiment of the present invention includes a filter housing adapted to mount on a substrate block having a plurality of flow paths and a filter cavity defined therein. The filter cavity is defined to extend in a generally horizontal direction when the low-profile filter is in use. A first flow passage is defined to connect an inlet of the filter housing to a first section of the filter cavity and a second flow passage is defined to connect a second section of the filter cavity to an outlet of the filter housing. A filter assembly is disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and second section of the filter cavity.

  • Patent number: 7534287
    Abstract: The present invention is directed to porous composite materials comprised of a porous base material and a powdered nanoparticle material. The porous base material has the powdered nanoparticle material penetrating a portion of the porous base material; the powdered nanoparticle material within the porous base material may be sintered or interbonded by interfusion to form a porous sintered nanoparticle material within the pores and or on the surfaces of the porous base material. Preferably this porous composite material comprises nanometer sized pores throughout the sintered nanoparticle material. The present invention is also directed to methods of making such composite materials and using them for high surface area catalysts, sensors, in packed bed contaminant removal devices, and as contamination removal membranes for fluids.
