Patent ID: 8641883

Claim:
A method of forming a three-dimensional structure comprising: forming a conductive layer on a substrate; patterning a first resist layer over the conductive layer, the first resist layer having contained therein a plurality of vias; electro-depositing an electrically conductive polymer in the vias so as to completely fill the vias and continuing electro-deposition until the conductive polymer extends above an upper surface of the first resist layer and progresses laterally to merge to form a continuous electrically conductive polymer layer on the upper surface of the first resist layer; patterning a second resist layer over the continuous electrically conductive polymer layer disposed atop the first resist layer, the second resist layer having contained therein a plurality of vias; and electro-depositing the electrically conductive polymer in the vias of the second resist layer so as to completely fill the vias and continuing electro-deposition until the conductive polymer extends above an upper surface of the second resist layer and progresses laterally to merge to form a continuous electrically conductive polymer layer on the upper surface of the second resist layer.
