Oxycarbosilane materials make excellent matrix materials for the formation of porous low-k materials using incorporated pore generators (porogens). The elastic modulus numbers measured for porous samples prepared in this fashion are 3-6 times higher than porous organosilicates prepared using the sacrificial porogen route. The oxycarbosilane materials are used to produce integrated circuits for use in electronics devices. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims.

摘要:
Substantially or roughly spherical micellar structures useful in the formation of nanoporous materials by templating are disclosed. A roughly spherical micellar structure is formed by organization of one or more spatially unsymmetric organic amphiphilic molecules. Each of those molecules comprises a branched moiety and a second moiety. The branched moiety can form part of either the core or the surface of the spherical micellar structure, depending on the polarity of the environment. The roughly spherical micellar structures form in a thermosetting polymer matrix. They are employed in a templating process whereby the amphiphilic molecules are dispersed in the polymer matrix, the matrix is cured, and the porogens are then removed, leaving nanoscale pores.

A nanoporous material exhibiting a lamellar structure is disclosed. The material comprises three or more substantially parallel sheets of an organosilicate material, separated by highly porous spacer regions. The distance between the centers of the sheets lies between 1 nm and 50 nm. The highly porous spacer regions may be substantially free of condensed material. For the manufacture of such materials, a process is disclosed in which matrix non-amphiphilic polymeric material and templating polymeric material are dispersed in a solvent, where the templating polymeric material includes a polymeric amphiphilic material. The solvent with the polymeric materials is distributed onto a substrate. Organization is induced in the templating polymeric material. The solvent is removed, leaving the polymeric materials in place. The matrix polymeric material is cured, forming a lamellar structure.

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.

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.
