Patent ID: 8262961

Claim:
A method, comprising: forming on a substrate a molding layer of a molding composition, said molding composition comprising one or more aromatic divinyl ethers; pressing a surface of a template into said molding layer, said template having a relief pattern on said surface, said molding layer filling voids in said relief pattern, said template not contacting said substrate; exposing said molding layer to actinic radiation, said actinic radiation converting said molding layer to a cured molding layer having thick and thin regions corresponding to said relief pattern; after exposing said molding layer to said actinic radiation, removing said template from said cured molding layer; after removing said template, filling said thin regions of said relief pattern with a backfill material; removing regions of said molding layer not protected by said backfill material to expose regions of said substrate; forming trenches in said exposed regions of said substrate; and after forming said trenches, removing any remaining molding layer and backfill material.
