Patent number: 10124529Abstract: Imprint lithography templates having leading and trailing edge borders are provided that achieve zero-gap imprinting between adjacent fields with full-feature height features provided in the pattern exclusion zones (PEZ) located between such fields. The leading edge borders include dummy features, e.g., elongated features directionally oriented parallel to the mesa edge, while the trailing edge border includes a recess extending to the mesa edges. When used in a step-and-repeat process, the trailing edge border overlaps edge portions of an adjacent imprinted field that were previously patterned by the leading edge border of the template, producing full-feature height features in the pattern exclusion zones between such fields, and avoiding gaps or open areas between such fields that otherwise lead to non-uniformity of downstream processes such as etch processes and CMP.Type: GrantFiled: December 10, 2014Date of Patent: November 13, 2018Assignee: Canon Nanotechnologies, Inc.Inventors: Gaddi S. Haase, Kosta S. Selinidis, Zhengmao Ye

Patent number: 9994715Abstract: A catalyst-free synthesis method for the formation of a metalorganic compound comprising a desired (first) metal may include, for example, selecting another (second) metal and an organic solvent, with the second metal being selected to (i) be more reactive with respect to the organic solvent than the first metal and (ii) form, upon exposure of the second metal to the organic solvent, a reaction by-product that is more soluble in the organic solvent than the metalorganic compound. An alloy comprising the first metal and the second metal may be first produced (e.g., formed or otherwise obtained) and then treated with the organic solvent in a liquid phase or a vapor phase to form a mixture comprising (i) the reaction by-product comprising the second metal and (ii) the metalorganic compound comprising the first metal. The metalorganic compound may then be separated from the mixture in the form of a solid.Type: GrantFiled: December 30, 2016Date of Patent: June 12, 2018Assignees: Sila Nanotechnologies Inc., Georgia Tech Research CorporationInventors: Gleb Yushin, James Benson, Danni Lei, Eugene Berdichevsky
