Abstract:
1. A process for forming a multilayer three-dimensional structure, comprising: (a) forming and adhering a first layer of material to a dielectric substrate or to a substrate containing at least one region of dielectric material, wherein the first layer comprises at least one structural material and at least one sacrificial material; (b) forming an adhering at least one additional layer to a previously formed layer, which may be the first layer or a layer formed subsequent to the forming of the first layer, to build up a three-dimensional structure from a plurality of adhered layers, wherein each of the at least one additional layers comprises at least one structural material and at least one sacrificial material; (c) after formation of the plurality of layers removing the at least one sacrificial material from multiple layers to reveal the three-dimensional structure; wherein the formation of the first layer of material additionally comprises: planarizing the at least one structural material and the at least one sacrificial material to set a boundary level of the first layer.
