Patent number: 11195969Abstract: A method of forming a metal silicide nanowire network that includes multiple metal silicide nanowires fused together in a disorderly arrangement on a substrate. The metal silicide nanowire network can be formed by applying a solution that contains silicon nanowires onto the substrate, forming a metal layer on the silicon nanowires, and performing a silicidation anneal such that the metal silicide nanowires are fused together in a disorderly arrangement, forming a mesh. After the silicidation anneal is performed, any unreacted silicon or metal can be selectively removed.Type: GrantFiled: August 3, 2018Date of Patent: December 7, 2021Assignee: International Business Machines CorporationInventors: Jeffrey P. Gambino, Derrick Liu, Daniel S. Vanslette

Patent number: 11056610Abstract: A method of forming a metal silicide nanowire network that includes multiple metal silicide nanowires fused together in an orderly arrangement on a substrate. The metal silicide nanowire network can be formed by printing a first set of multiple parallel silicon nanowires on the substrate and printing a second set of multiple parallel silicon nanowires over the first set of multiple parallel silicon nanowires such that said first set is perpendicular to said second set. A metal layer can be formed on the silicon nanowires. A silicidation anneal process is performed such that metal silicide nanowires are formed and fused together in an orderly arrangement, forming a grid network. After the silicidation anneal is performed, any unreacted silicon or metal can be selectively removed.Type: GrantFiled: August 3, 2018Date of Patent: July 6, 2021Assignee: International Business Machines CorporationInventors: Jeffrey P.

Patent number: 9312426Abstract: Disclosed are embodiments of a structure with a metal silicide transparent conductive electrode, which is commercially viable, robust and safe to use and, thus, optimal for incorporation into devices, such as flat panel displays, touch panels, solar cells, light emitting diodes (LEDs), organic optoelectronic devices, etc. Specifically, the structure can comprise a substrate (e.g., a glass or plastic substrate) and a transparent conducting film on that substrate. The transparent conducting film can comprise a metal silicide nanowire network. For example, in one embodiment, the metal silicide nanowire network can comprise multiple metal silicide nanowires fused together in a disorderly arrangement so that they form a mesh. In another embodiment, the metal silicide nanowire network can comprise multiple metal silicide nanowires patterned so that they form a grid. Also disclosed herein are various different method embodiments for forming such a structure.Type: GrantFiled: December 7, 2011Date of Patent: April 12, 2016Assignee: International Business Machines CorporationInventors: Jeffrey P.

Patent number: 9245850Abstract: Disclosed herein are through silicon vias (TSVs) and contacts formed on a semiconductor material, methods of manufacturing, and design structures. The method includes forming a contact hole in a dielectric material formed on a substrate. The method further includes forming a via in the substrate and through the dielectric material. The method further includes lining the contact hole and the dielectric material with a metal liner using a deposition technique that will avoid formation of the liner in the viaformed in the substrate. The method further includes filling the contact hole and the via with a metal such that the metal is formed on the liner in the contact hole and directly on the substrate in the via.Type: GrantFiled: June 11, 2014Date of Patent: January 26, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Jeffrey P.
