Patent ID: 7488686

Claim:
A method for forming at least a portion of a three-dimensional structure from a plurality of stacked and adhered layers, comprising: forming a plurality of stacked and adhered layers to form the at least portion of the three-dimensional structure, wherein the formation of each layer comprises depositing and patterning a first conductive material, depositing a second conductive material, and planarizing the first and second conductive materials: wherein the formation of at least one layer comprises: (a) depositing and patterning a first conductive material on a substrate or previously formed layer to obtain a desired pattern having at least one protrusion of the first conductive material having a surface and at least one opening extending from the surface through a thickness of the first conductive material to the substrate or previously formed layer; (b) treating the surface of the first conductive material to decrease susceptibility of the surface to receive a second conductive material which is to be deposited; (c) depositing the second conductive material, such that deposition occurs with a higher selectivity to one or more regions defined by the at least one opening, wherein the higher selectivity results, at least in part, from the treating of the surface of the first conductive material; (d) removing an effect of the treating of the surface of the first conductive material.
