The substrate comprises porous microcircuit substrate materials with surface pores optionally opening into subsurface pores. The organic polymer has a molecular weight greater than about 5,000 to greater than about 10,000 and a glass transition temperature greater than about 200° C. up to about the processing temperature required for forming the imaging layer and antireflective layer in a microcircuit, e.g., greater than about 225° C.

Abstract: Methods of minimizing or eliminating plasma damage to low k and ultra low k organosilicate intermetal dielectric layers are provided. The reduction of the plasma damage is effected by interrupting the etch and strip process flow at a suitable point to add an inventive treatment which protects the intermetal dielectric layer from plasma damage during the plasma strip process. Reduction or elimination of a plasma damaged region in this manner also enables reduction of the line bias between a line pattern in a photoresist and a metal line formed therefrom, and changes in the line width of the line trench due to a wet clean after the reactive ion etch employed for formation of the line trench and a via cavity. The reduced line bias has a beneficial effect on electrical yields of a metal interconnect structure.

Abstract: 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.

Abstract: 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.

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.
