Patent ID: 7691275

Claim:
A method comprising the steps of: a) dispensing a quantity of dielectric precursor liquid onto a substrate, wherein the substrate has been treated with an adhesion promoter; b) pressing a multi-tiered template into the dielectric precursor liquid as it resides on the substrate, wherein the multi-tiered template has been treated with a fill/release agent; c) photo-curing the dielectric precursor liquid as it resides between the substrate and the multi-tiered template to form a template-bound photo-cured multi-tiered patterned dielectric material; d) removing the multi-tiered template from the multi-tiered patterned dielectric material to yield a photo-cured multi-tiered patterned dielectric structure on the substrate; e) clearing residual material from the photo-cured multi-tiered patterned dielectric structure, wherein such material otherwise prevents contact with the underlying substrate; f) thermally curing/baking the photo-cured multi-tiered patterned dielectric structure to form a thermally-cured multi-tiered patterned dielectric structure; g) depositing copper in the thermally-cured multi-tiered patterned dielectric structure to form a filled multi-tiered patterned dielectric structure with a copper overfill layer; and h) removing the copper overlayer.
