Publication number: 20040185242Abstract: This invention relates to a general method to surface modify porous membranes with a free radical polymerized polymer coating in a layer which is less than the thickness of the membrane. Another object of this invention relates to a general method to surface modify porous membranes with a free radical polymerized polymer coating to a predetermined and controlled depth from a first facial surface. Another object of this invention is to provide a general method to surface modify porous membranes with a free radical polymerized polymer coating into a pattern on one or both facial surfaces, the pattern maintaining its form to a controlled depth into the membrane. Membrane modification is spatially controlled through the use of a polymerization preventing agent (PPA), which prevents modification from occurring in defined spatially volumes of the membrane. The invention relates to porous membranes surface modified by the methods described.Type: ApplicationFiled: March 21, 2003Publication date: September 23, 2004Inventor: John Charkoudian

Patent number: 6780499Abstract: A porous, low-k dielectric film that has good mechanical properties as well as a method of fabricating the film and the use of the film as a dielectric layer between metal wiring features are provided. The porous, low-k dielectric film includes a first phase of monodispersed pores having a diameter of from about 1 to about 10 nm that are substantially uniformly spaced apart and are essentially located on sites of a three-dimensional periodic lattice; and a second phase which is solid surrounding the first phase. Specifically, the second phase of the film includes (i) an ordered element that is composed of nanoparticles having a diameter of from about 1 to about 10 nm that are substantially uniformly spaced apart and are essentially arranged on sites of a three-dimensional periodic lattice, and (ii) a disordered element comprised of a dielectric material having a dielectric constant of about 2.8 or less.Type: GrantFiled: May 3, 2001Date of Patent: August 24, 2004Assignee: International Business Machines CorporationInventors: Stephen McConnell Gates, Christopher B. Murray, Satyanarayana V. Nitta, Sampath Purushothaman

Patent number: RE39354Abstract: A laser-sinterable powder product has been prepared having unique properties which allow the powder to be sintered in a selective laser sintering machine to form a sintered part which is near-fully dense. For most purposes, the sintered part is indistinguishable from another part having the same dimensions made by isotropically molding the powder. In addition to being freely flowable at a temperature near its softening temperature, a useful powder is disclosed that has a two-tier distribution in which substantially no primary particles have an average diameter greater than 180 ?m, provided further that the number average ratio of particles smaller than 53 ?m is greater than 80%, the remaining larger particles being in the size range from 53 ?m to 180 ?m. A powder with slow recrystallization rates, as evidenced by non-overlapping or slightly overlapping endothermic and exothermic peaks in their differential scanning calorimetry characteristics for scan rates of on the order of 10° C. to 20° C.Type: GrantFiled: October 24, 2002Date of Patent: October 17, 2006Assignee: 3D Systems, Inc.Inventors: Elmer Douglas Dickens, Jr., Biing-Lin Lee, Glenn Alfred Taylor, Angelo Joseph Magistro, Hendra Ng, Kevin P.
