Patent number: 11820663Abstract: A membrane is electrically charged to a polarity. A surface of carbon nanotubes (CNTs) in a solution is caused to acquire a charge of the polarity. The solution is filtered through the membrane. An electromagnetic repulsion between the membrane of the polarity and the CNTs of the polarity causes the CNTs to spontaneously align to form a crystalline structure.Type: GrantFiled: February 14, 2018Date of Patent: November 21, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Abram L. Falk, Damon B. Farmer, Lynne M. Gignac

Patent number: 8679970Abstract: A semiconductor structure including a highly reliable high aspect ratio contact structure in which key-hole seam formation is eliminated is provided. The key-hole seam formation is eliminated in the present invention by providing a densified noble metal-containing liner within a high aspect ratio contact opening that is present in a dielectric material. The densified noble metal-containing liner is located atop a diffusion barrier and both those elements separate the conductive material of the inventive contact structure from a conductive material of an underlying semiconductor structure. The densified noble metal-containing liner of the present invention is formed by deposition of a noble metal-containing material having a first resistivity and subjecting the deposited noble metal-containing material to a densification treatment process (either thermal or plasma) that decreases the resistivity of the deposited noble metal-containing material to a lower resistivity.Type: GrantFiled: May 21, 2008Date of Patent: March 25, 2014Assignee: International Business Machines CorporationInventors: Chih-Chao Yang, Lynne M.
