Patent number: 8172923Abstract: 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.Type: GrantFiled: January 21, 2009Date of Patent: May 8, 2012Assignee: Entegris, Inc.Inventors: Christopher Vroman, Marshall Randolph

Patent number: 7967882Abstract: 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.Type: GrantFiled: October 4, 2010Date of Patent: June 28, 2011Assignee: Entegris, Inc.Inventors: Anthony DiPrizio, Nathan Abbott, Christopher Vroman, Rajnikant B. Patel, Eric McNamara

Patent number: 7534287Abstract: 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.Type: GrantFiled: December 10, 2007Date of Patent: May 19, 2009Assignee: Entegris, Inc.Inventors: Robert Zeller, Christopher Vroman
