Abstract:
1. A process for forming a multilayer three-dimensional structure, comprising: (a) providing data descriptive of the three-dimensional structure; (b) processing the data to derive cross-sectional data descriptive of a plurality of cross-sections of the three-dimensional structure; (c) processing the cross-sectional data to derive modified cross-sectional data comprising polygons, where each individual polygon encloses only a positive area and the modified cross-sectional data for each cross-section comprises by a plurality of such polygons; (d) using the modified cross-sectional data in a process for forming a patterned contact mask; (e) forming and adhering a layer of material to a substrate; (f) repeating the forming and adhering operation a plurality of times to build up a three-dimensional structure from a plurality of adhered layers, wherein each successive layer is adhered to a previously formed layer, wherein the formation of at least one layer comprises using the patterned contact mask to pattern a surface of the substrate or of a previously deposited material.
