Leah Langsdorf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8535454
    Abstract: Embodiments in accordance with the present invention encompass polymer compositions that are useful in the assembly of microelectronic components onto a variety of substrate materials. Such polymer compositions providing for both holding the microelectronic components at desired positions on a substrate, providing fluxing for the solder bonding of such components to the substrate and remaining in place as an underfill for such components.
    Type: Grant
    Filed: November 18, 2011
    Date of Patent: September 17, 2013
    Assignee: Promerus, LLC
    Inventors: Christopher Apanius, Andrew Bell, Leah Langsdorf, W. C. Peter Tsang
  • Patent number: 8470944

  • Publication number: 20120031556
    Abstract: Embodiments according to the present invention relate to sacrificial polymer compositions that include polycarbonate polymers having repeat units derived from stereospecific polycyclic 2,3-diol monomers. The sacrificial polymer compositions also include an acid generator that is selected from at least one photoacid generator and/or at least one thermal acid generator. In addition, embodiments according to the present invention relate to a method of forming a structure that includes a three-dimensional space interposed between a substrate and an overcoat layer, and a method of temporarily bonding first and second substrates together, which make use of the polycarbonate polymers.

  • Publication number: 20060025540
    Abstract: The present invention relates to polycyclic polymers, methods for producing polycyclic polymers, and methods for their use as photoresists in the manufacture of integrated circuits. In one embodiment, the present invention relates to photoresist compositions formed from the polymerization of at least one halogenated polycyclic monomer or hydrohalogenated polycyclic monomer. In another embodiment, the present invention relates to photoresist compositions formed from the co-polymerization of at least one halogenated polycyclic monomer or hydrohalogenated polycyclic monomer with at least one non-halogenated polycyclic monomer. Additionally, the present invention relates to methods by which to post-treat such photoresist compositions in order to obtain one or more of: (1) a reduction in optical density of the polymer composition; and (2) a reduction in the amount of residual metal and/or monomer in the polymer composition.

  • Patent number: 6328833
    Abstract: Tufted carpeting can be manufactured employing polyurethane adhesives and cured face up without dripping, when one or more drip-reducing process steps of adding a non-Newtonian thickener to the adhesive or forming a viscosified or cured film on the outer surface of the adhesive are practiced prior to entry of the greige good into the curing oven.
