Patent ID: 7271888

Claim:
A fabrication process for forming a multi-layer three-dimensional structure, comprising: (a) forming and adhering a layer of material to a previously formed layer and/or to a substrate, wherein the layer comprises a desired pattern of at least one material, wherein one or more contact pads exist on the substrate or on a previously formed layer; (b) subjecting the at least one material to a planarization operation; (c) locating a measurement probe in contact with the one or more contact pads and in contact with material that was subject to the planarization operation and extracting data from the fixture concerning a measured height of planarized material at at least one point relative to a desired reference point or plane; (d) comparing the measured height of material to a desired height for the material; (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; (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.
