Patent ID: 6982058

Claim:
A method of manufacturing a three dimensional structure having at least a first layer and a second layer, said method comprising: providing a substrate layer; applying a first coating of a photoimageable material to the substrate layer; preparing a first mask having a pattern corresponding to the first layer of the three dimensional structure to be manufactured; exposing the first coating of the photoimageable material with an exposure source through the first mask such that the first layer of the three dimensional structure is provided; applying a second coating of the photoimageable material subsequent to the first layer of the three dimensional structure; preparing a second mask having a pattern corresponding to the second layer of the three dimensional structure to be manufactured; exposing the second coating of the photoimageable material with the exposure source through the second mask such that the second layer of the three dimensional structure is provided; and developing and removing regions of said first and second coatings that do not correspond to a layer of the three dimensional structure.
