Patent number: 8898810Abstract: A method for functionalizing cantilevers is provided that includes providing a holder having a plurality of channels each having a width for accepting a cantilever probe and a plurality of probes. A plurality of cantilever probes are fastened to the plurality of channels of the holder by the spring clips. The wells of a well plate are filled with a functionalization solution, wherein adjacent wells in the well plate are separated by a dimension that is substantially equal to a dimension separating adjacent channels of the plurality of channels. Each cantilever probe that is fastened within the plurality of channels of the holder is applied to the functionalization solution that is contained in the wells of the well plate.Type: GrantFiled: December 23, 2013Date of Patent: November 25, 2014Assignees: UT-Battelle, LLC, University of Tennesse Research FoundationInventors: Barbara R. Evans, Ida Lee

Patent number: 8484758Abstract: The present invention includes an apparatus that holds the probes to a solid support throughout the passages of the functionalization process, thus avoiding user-dependent breakage or damage of the fragile AFM cantilevers. The apparatus allows the tips of the AFM probes to be placed face-down, which avoids the deposition of contaminants on their functional side. The device also allows functionalizing the tips with small liquid volumes and cleaning. The present invention includes a functionalization process preventing non-specific adsorption of molecules on the tip.Type: GrantFiled: March 29, 2010Date of Patent: July 9, 2013Assignee: Centro de Investigacion Cooperativa en Biomateriales (CIC Biomagune)Inventors: Elena Martines, Isabel Garcia Martin, Soledad Penades Ullate

Patent number: 8468611Abstract: Improved nanolithography components, systems, and methods are described herein. The systems and methods generally employ a resistively heated atomic force microscope tip to thermally induce a chemical change in a surface. In addition, certain polymeric compositions are also disclosed.Type: GrantFiled: June 1, 2010Date of Patent: June 18, 2013Assignee: Georgia Tech Research CorporationInventors: Elisa Riedo, Seth R. Marder, Walt A. de Heer, Robert J. Szoskiewicz, Vamsi K. Kodali, Simon C. Jones, Takashi Okada, Debin Wang, Jennifer E. Curtis, Clifford L. Henderson, Yueming Hua

Patent number: 8387160Abstract: A resist medium in which features are lithographically produced by scanning a surface of the medium with an AFM probe positioned in contact therewith. The resist medium comprises a substrate; and a polymer resist layer within which features are produced by mechanical action of the probe. The polymer contains thermally reversible crosslinkages. Also disclosed are methods that generally includes scanning a surface of the polymer resist layer with an AFM probe positioned in contact with the resist layer, wherein heating the probe and a squashing-type mechanical action of the probe produces features in the layer by thermally reversing the crosslinkages.Type: GrantFiled: October 7, 2010Date of Patent: February 26, 2013Assignee: International Business Machines CorporationInventors: Michel Despont, Urs T. Duerig, Jane E. Frommer, Bernd W. Gotsmann, James L. Hedrick, Craig Jon Hawker, Robert D. Miller

Patent number: 8216746Abstract: Provided is a method of correcting a defect in an extreme ultraviolet (EUV) mask. A monomolecular film is chemically bonded onto a surface of a repair tip. The repair tip is positioned over a defect disposed on the EUV mask, so that the monomolecular film bonded onto the repair tip can also bond to the defect. The repair tip is then moved away from the EUV mask so that the defect is separated from the EUV mask and thus removing the defect in the EUV mask.Type: GrantFiled: July 16, 2010Date of Patent: July 10, 2012Assignee: Hynix Semiconductor Inc.Inventor: Jun Chun

Patent number: 8046843Abstract: An instrument includes a probe having a porous tip, a tip positioning apparatus to position the tip with respect to a sample material, a probe positioning apparatus to position the probe and sample material with respect to each other, and a controller. The controller controls the probe positioning apparatus in positioning the probe over the sample and controls the tip positioning apparatus in lowering the tip into the sample material to produce an interaction between the porous tip and the sample material.Type: GrantFiled: April 14, 2009Date of Patent: October 25, 2011Assignee: General Nanotechnology LLCInventor: Victor B.
