  • Publication number: 20060091322
    Abstract: 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.

  • Publication number: 20050243469
    Abstract: A slider assembly is provided comprising a plurality of sliders bonded by a debondable solid encapsulant comprised of different first and second polymers The solid encapsulant is comprised of a polymer prepared by polymerizing an encapsulant fluid comprising a homogeneous mixture of first and second constituents. The first constituent is comprised of a first monomer suitable for in situ polymerization to form the first polymer. The second constituent is comprised of the second polymer or a second monomer suitable for in situ polymerization to form the second polymer. The first constituent does not substantially react with the second constituent. Each slider has a surface that is free from the encapsulant. The encapsulant-free surfaces are coplanar to each other. Also provided are methods for forming the assembly and methods for patterning a slider surface using the encapsulant.

  • Publication number: 20050202338
    Abstract: Crosslinked particles are provided that are useful in the manufacture of dielectric materials for use in electronic devices such as integrated circuits. The crosslinked particles are prepared by activating crosslinkable groups on synthetic polymer molecules, where the crosslinkable groups are inert until activated and, when activated, undergo an irreversible intramolecular crosslinking reaction to form crosslinked particles.

  • Publication number: 20050068680
    Abstract: A slider assembly is provided comprising a plurality of sliders bonded by a debondable solid encapsulant. The solid encapsulant is comprised of a polymer prepared by polymerizing a mixture of first and second monomers in a nonstoichiometric ratio effective to render the encapsulant debondable. Each slider has a surface that is free from the encapsulant. The encapsulant-free surfaces are coplanar to each other. Also provided are methods for forming the assembly and methods for patterning a slider surface using the encapsulant.

  • Publication number: 20050067373
    Abstract: An encapsulant fluid is provided comprising a mixture of a diene-containing compound and a dienophilic compound. At least one of the diene-containing and the dienophilic compounds is protected so that the compounds do not substantially react with each other at room temperature. The diene-containing and the dienophilic compounds undergo a reversible Diels-Alder polymerization reaction at a polymerization temperature above room temperature to form a solid debondable polymeric encapsulant. Also provided are methods for forming slider assemblies and methods for patterning a slider surface using the encapsulant.

  • Publication number: 20050047307
    Abstract: 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.

  • Publication number: 20050050258
    Abstract: An approach is presented for designing the polymeric recording layer for nanometer scale thermomechanical storage devices. Cross linked polymers are used as the recording layers in atomic force microscopy data storage devices, giving significantly improved performance when compared to the previously reported linear polymers. This results in superior wear resistance and enhanced erasing, critical features for the long-term multiple read-write cycles of such thermomechanical storage devices. In addition, this ability to introduce a predetermined extent of cross linking allows fine tuning of the thermal and force parameters in the R/W/E (read-write-erase) cycles.
