Patent ID: 7351321

Claim:
A method for fabricating a multi-layer three-dimensional structure, comprising: (i) forming a first layer, comprising: a) providing a first mask in contact with a substrate, wherein the mask has a first pattern of openings therein; b) electrodepositing a first pattern of a first material from a source of the first material onto said substrate using the first mask to form a portion of a first layer; c) removing the first mask from the substrate; d) providing a second mask in contact with the substrate, and/or the first material, wherein the mask has a second pattern of openings therein; e) electrodepositing a second pattern of a second material from a source of the second material onto said substrate and/or the first material using the second mask to form a portion of the first layer; and f) removing the second mask from the substrate and/or first material; (ii) building additional layers adjacent to and adhered to previously formed layers to build up the multi-layer three-dimensional structure, wherein the first material comprises a sacrificial material and the second material comprises a structural material, and (iii) releasing the structural material from the sacrificial material after the build up of the multi-layer structure.
