Publication number: 20080013437Abstract: A data storage device comprises a storage medium for storing data in the form of marks and at least one probe for scanning the storage medium. The storage medium may be comprised in a substrate. The probe comprises a cantilever that comprises terminals serving as electrical contacts an being during operation of the probe mechanically fixed to a probe-holding structure, which may be a common frame of the data storage device. A probe further comprises a supporting structure, to which the terminals are mechanically directly coupled or coupled via hinges and which extends away from the terminals. A tip with a nanoscale apex is provided. A beam structure comprises a heating resistor and is attached at ends to the supporting structure. The beam structure is thinned at least in a direction parallel to an axis of the tip compared to an area of the supporting structure abutting the beam structure.Type: ApplicationFiled: January 13, 2006Publication date: January 17, 2008Inventors: Thomas Albrecht, Michel Despont, Urs Duerig, Mark Lantz, Hugo Rothuizen, Dorothea Wiesmann Rothuizen

Publication number: 20070193347Abstract: The present invention provides a novel method for determining the mechanical properties of the surfaces of materials including thin films. Generally, the method is comprised of laterally scanning the surface of the film with an array of cantilever tips varying temperature, load and time to obtain a measurement of mechanical properties, such as hardness and glass transition temperature. The method can be used to obtain mechanical properties of films that would otherwise be unobtainable using standard methods.Type: ApplicationFiled: February 21, 2006Publication date: August 23, 2007Applicant: International Business Machines CorporationInventors: Richard Bradshaw, Urs Duerig, Bernd Gotsmann

Publication number: 20070196645Abstract: An approach is presented for designing a polymeric layer for nanometer scale thermo-mechanical storage devices. Cross-linked polyimide oligomers are used as the recording layers in atomic force data storage device, giving significantly improved performance when compared to previously reported cross-linked and linear polymers. The cross-linking of the polyimide oligomers may be tuned to match thermal and force parameters required in read-write-erase cycles. Additionally, the cross-linked polyimide oligomers are suitable for use in nano-scale imaging.Type: ApplicationFiled: February 21, 2006Publication date: August 23, 2007Applicant: International Business Machines CorporationInventors: Urs Duerig, Jane Frommer, Bernd Gotsmann, Erik Hagberg, James Hedrick, Armin Knoll, Victor Lee, Teddie Magbitang, Robert Miller, Russell Pratt, Charles Wade, Johannes Windeln

Publication number: 20060091322Abstract: 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.Type: ApplicationFiled: October 29, 2004Publication date: May 4, 2006Inventors: Michel Despont, Urs Duerig, Jane Frommer, Bernd Gotsmann, James Hedrick, Craig Hawker, Robert Miller

Publication number: 20050281174Abstract: The present invention provides data storage devices, systems and methods. An example device includes: a storage medium for storing data in the form of marks; and at least one probe. The probe(s) and storage medium are operable to move relative to each other, with each probe comprising a tip facing the storage medium and having a force creating unit associated thereto. The force creating units are operable to create a force acting between the tip and said storage medium. The data storage device is operable to erase an indentation mark in the storage medium by way of controlling the force creating unit for creating at least one erase force pulse with a force rise time being less than or equal to the order of 1 microsecond.Type: ApplicationFiled: June 22, 2005Publication date: December 22, 2005Applicant: International Business Machines CorporationInventors: Bernd Gotsmann, Urs Duerig, Charalamoos Pozidie, Hugo Rothuizen, Gerd Binnig

Publication number: 20050130551Abstract: A method for forming a microstructures is described. The method comprises: depositing a seed material on a substrate; growing a nanotube from the seed material; depositing microstructure material on the substrate to embed the nanotube in the microstructure material; and, detaching the substrate to release the microstructure. The resulting mictostructure comprises a body portion and a nanotube embedded in the body portion.Type: ApplicationFiled: November 21, 2002Publication date: June 16, 2005Inventors: Graham Cross, Michel Despont, Urs Duerig, Gregoire Genolet, Reto Schlittler

Publication number: 20050047307Abstract: A data storage medium from which information is reproduced by scanning a surface of the medium with a probe-based tip, such as an Atomic Force Microscope (AFM) tip positioned in contact therewith. The medium comprises a substrate; and a polymer recording surface within which data bit values are determined by the topographical state at the bit location. The polymer contains thermally reversible crosslinkages. The data bit value is a function of the depth of the pit at the bit location.Type: ApplicationFiled: August 29, 2003Publication date: March 3, 2005Inventors: Jane Frommer, Robert Miller, Craig Hawker, Urs Duerig, Bernd Gotsmann, Peter Vettiger, Mark Lantz

Publication number: 20050037560Abstract: A data storage medium is introduced. The data storage medium from which information is reproduced by scanning a surface of the medium with a tip positioned in contact therewith comprises a recording layer within which data values are determined by the topographical state at the data item location. The material of said recording layer comprises a component that is generating an etchant. The etchant removes the naturally occurring surface oxide layer of the tip which keeps the tip sharp and works against tip wear.Type: ApplicationFiled: July 20, 2004Publication date: February 17, 2005Applicant: International Business Machines CorporationInventors: Urs Duerig, Bernd Gotsmann, Walter Haeberle, Mark Lantz

Publication number: 20050018588Abstract: A data storage device is introduced. The data storage device comprises a write head. The write head comprises a heating element and a tip. The write head scans a data storage medium, wherein in an operation mode of the data storage device the tip is in contact with a surface of the data storage medium and heat is applied to the tip by means of the heating element. In order to achieve a good thermal contact between the tip and the data storage medium, the tip comprises a carbon element that is at least partially in contact with the surface in that operation mode. Such a write head can also be applied in the field of scanning probe lithography.Type: ApplicationFiled: May 24, 2004Publication date: January 27, 2005Inventors: Urs Duerig, Bernd Gotsmann, Mark Lantz, Peter Vettiger

Patent number: 6791433Abstract: Scheme for processing an input signal A(t) by N resonators (17), each having parameters characterizing it, to generate N individual output signals. Then each of the N individual output signals is weighted using a corresponding weight to generate N individual weighted output signals which are superposed to obtain M output signals C(t). One of the parameters or the weight depend on a time signal P(t).Type: GrantFiled: July 13, 2000Date of Patent: September 14, 2004Assignee: International Business Machines CorporationInventors: Urs Duerig, Peter Bloechl, Oliver Folini
