Abstract:
1. A method for forming a three-dimensional structure, comprising: (a) providing a substrate on which to build up multiple layers of multiple deposited materials; (b) depositing two or more materials to form a layer of desired cross-sectional configuration adhered to the substrate or a previous formed layer; (c) repeating the operation of (b) one or more times to build up a plurality of layers on the substrate, such that each layer has a desired cross-sectional configuration which when taken in combination with other cross-sectional configurations result in the formation of at least one removal region, occupied by at least one conductive removable material, that is multiple layers in thickness and that is in contact with a retention region where the contact between the at least one retention region and the at least one removal region is via a conductive barrier material, (d) removing material from the at least one removal region by a removal operation to form at least one multi-layer deposition region while not removing material from the at least one retention region as the barrier material inhibits the removal operation from accessing and removing any removable material located in the at least one retention region; (e) filling the deposition region with a desired structural material.
