Accordingly, in some certain embodiments, steps (1) and (2) may be repeated, allowing the growth rates of the particles to be determined. A plurality of monomers may be employed to identify different types of particles on the same substrate. The method is useful in detecting copper particles on silicon substrates.Type: GrantFiled: May 9, 2006Date of Patent: July 3, 2007Assignee: Micron Technology, Inc.Inventor: Terry L. Gilton

Patent number: 6962962Abstract: The invention provides an optically active polymer which is a product obtained by polymerizing a chiral alkoxy-substituted phenylacetylene such as p-(2-methylbutoxy)phenylacetylene, of which the 2-methylbutoxy group has chirality, in an organic solvent such as triethylamine in the presence of a rhodium complex compound as a polymerization catalyst. The optically active polymer exhibits a much larger optical rotation than the monomeric compound per se and is colored in different colors of, e.g., yellow and black, depending on the organic solvent used for polymerization. The yellow polymer turns to black by exposure to the vapor of a specific organic solvent such as chloroform and returns to yellow by re-precipitation from a chloroform solution with addition of methyl alcohol as a precipitant.Type: GrantFiled: May 8, 2003Date of Patent: November 8, 2005Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Masayoshi Tabata, Yasuteru Mawatari

Patent number: 6953868Abstract: The present invention is a method for oxyfunctionalizing, that is, introducing oxygen functionality to, a polyolefin such as polypropylene and poly(ethylene-alt-propylene). The polyolefin is contacted with an oxygen source such as a persulfate and catalytic amounts of a metal porphyrin complex under mild conditions to yield an oxyfunctionalized polymer that has a polydispersity that is very similar to that of the starting polymer.Type: GrantFiled: April 26, 2004Date of Patent: October 11, 2005Assignees: Dow Global Technologies Inc., Regents of the University of MinnesotaInventors: Nicole K. Boaen, Marc A. Hillmyer, Stephen F. Hahn
