Patent ID: 8603584

Claim:
A method of forming a structure, comprising: forming on a substrate a precursor dielectric layer of a polymerizable composition comprising one or more polyhedral silsesquioxane oligomers each having one or more polymerizable groups; pressing a surface of a template into said precursor dielectric layer, said template having a relief pattern on said surface, said precursor dielectric layer filling voids in said relief pattern; polymerizing said precursor dielectric layer and converting said precursor dielectric layer to a dielectric layer having first and second regions corresponding to said relief pattern, said first regions thicker than said second regions; removing said template; removing said second regions of said dielectric layer; and thermally curing said dielectric layer to decompose carbonaceous materials of said polymerizable composition to create a porous dielectric layer; and filling spaces between said first regions of said porous dielectric layer with an electrically conductive material.
