  • 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: 20050191418
    Abstract: UV molding from elastomeric masters on thin bendable backplanes that allow replication of UV-cured resist patterns with high accuracy is disclosed. This design accommodates large substrate topographies, has improved de-molding properties, and facilitates two-in-one lithography and assembly of the sliders on topographically structured elastomeric sticky pads. The combination of sticky pad assembly and two-in-one lithography allows an all-in-one harmony process based on UV-molding. These features cure prior art technical problems of the harmony process while significantly reducing cost.

  • Publication number: 20050191582
    Abstract: A mechanically releasable slider process utilizes silicone rubber or PDMS to take the function of a planarization material for individual sliders or slider rows. Mechanical debonding takes advantage of the rubber-elastic property of PDMS. A gripper is used in a virtually solvent-free, air bearing patterning UV-molding process and resist-based processes. A PDMS-based fixture is used during both the lapping process and the photo or UV-mold patterning of the ABS surface. This fixture can mechanically hold sliders by large area reversible adhesion while allowing gimbaling, electrical connection, actuation, UV-molding or photolithography, and mechanical release, thus reducing the number of slider manipulations to two.

  • 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.
