Patent ID: 7517462

Claim:
A process for forming a multilayer three-dimensional structure on a dielectric substrate, 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; (b) forming and adhering at least one layer to a previously formed layer to build up a three-dimensional structure from a plurality of adhered layers; wherein the formation of the first layer of material comprises: (i) depositing a first seed layer material onto the substrate including at least some portions of the substrate that are not to receive a selected one of a structural material and sacrificial material; (ii) depositing a selected one of structural material and sacrificial material onto the first seed layer material over those portions of the substrate that are to receive the selected one of structural material and sacrificial material, wherein the portions that are to receive the selected one are less than all portions of the substrate; (iii) removing portions of the first seed layer material that are not located between the selected one and the substrate or located adjacent to the selected one; (iv) after removing portions of the first seed layer depositing a second seed layer material onto those portions of the substrate that are to receive a non-selected one of the structural material and sacrificial material; (v) depositing the non-selected one of the structural material and sacrificial material onto the second seed layer material over those portions of the substrate that are to receive the non-selected one of structural material and sacrificial material; (vi) planarizing the deposited selected one of the structural material and sacrificial material and the deposited non-selected one of the structural material and sacrificial material to a height corresponding to a desired thickness of the first layer.
