    摘要: A nanoparticle which includes a multi-armed core and surface decoration which is attached to the core is prepared. A multi-armed core is provided by any of a number of possible routes, exemplary preferred routes being living anionic polymerization that is initiated by a reactive, functionalized anionic initiator and ε-caprolactone polymerization of a bis-MPA dendrimer. The multi-armed core is preferably functionalized on some or all arms. A coupling reaction is then employed to bond surface decoration to one or more arms of the multi-armed core. The surface decoration is a small molecule or oligomer with a degree of polymerization less than 50, a preferred decoration being a PEG oligomer with degree of polymerization between 2 and 24. The nanoparticles (particle size ≦10 nm) are employed as sacrificial templating porogens to form porous dielectrics. The porogens are mixed with matrix precursors (e.g., methyl silsesquioxane resin), the matrix vitrifies, and the porogens are removed via burnout. Greater porosity reduces the dielectric constant k of the resulting dielectrics. The porous dielectrics are incorporated into integrated circuits as lower k alternatives to silicon dioxide.

    摘要: 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.
