Jonathan C. Shaw 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: 11751382
    Abstract: Methods of forming a DRAM bit line to improve line edge roughness (LER) and lower resistance are described. The method comprises implanting an inert species into a bit line metal layer having a first grain size on a substrate to form an amorphized bit line metal layer having a second grain size smaller than the first grain size. A film stack is then deposited on the amorphized bit line metal layer. The film stack and amorphized bit line metal layer are etched to form a patterned film stack on the substrate. The patterned film stack on the substrate is thermally annealed.
    Type: Grant
    Filed: April 11, 2022
    Date of Patent: September 5, 2023
    Assignee: Applied Materials, Inc.

  • Patent number: 4568498
    Abstract: The reaction of the lithium enolate of acetaldehyde, LiOCHCH.sub.2, with achlorocyclotriphosphazene, N.sub.3 P.sub.3 Cl.sub.6, lead to the series of (vinyloxy)chlorocyclotriphosphazenes, N.sub.3 P.sub.3 Cl.sub.6-n (OCH.dbd.CH.sub.2).sub.n (n=1-6). The nongeminal pathway is favored. These materials undergo homopolymerization reaction and can be copolymerized with a wide variety of organic monomers. The resulting polymeric systems incorporate certain properties such as fire retardancy and are chemically bonded to the polymer rather than an additive.
