Abstract:
1. A fabrication process for forming a multi-layer three-dimensional structure, comprising: (a) forming and adhering a given layer comprising at least two deposited materials to a previously formed layer or to a substrate, wherein one or more contact pads exist on the substrate or on a previously formed layer and are thin enough not to undergo planarization during formation of the given layer; (b) subjecting the at least two materials of the given layer to a planarization operation, comprising: (c) positioning a second fixture in contact with the one or more contact pads and in contact with the deposited materials that were subjected to the planarization operation and extracting data from the second fixture concerning a measured height of the planarized deposited materials at at least one point relative to a desired reference point or plane defined by the one or more contact pads; (d) comparing the measured height of the planarized deposited materials to a desired height for the deposited materials; (e) if the measured and desired heights are not within a desired tolerance, repeating operations (b)-(d) until the measured and desired heights are within the desired tolerance; and (f) repeating the forming and adhering of operation (a) one or more times to form the three-dimensional structure from a plurality of adhered layers.
