Abstract:
1. A method of fabricating a three-dimensional microstructure, comprising the steps of: forming a prototypic structure in accordance with data corresponding to a designed three-dimensional shape of the three-dimensional microstructure by scanning a sample with a beam produced by a charged-particle beam system while controlling processing conditions thereof; comparing the shape of the formed prototypic structure with the designed three-dimensional shape of the three-dimensional microstructure to identify differences between the shape of the prototypic structure and the designed three-dimensional shape of the three-dimensional microstructure; and processing the prototypic structure to correct the differences identified in the comparing step by scanning the prototypic structure with a beam produced by the charged-particle beam system while adjusting the processing conditions thereof to thereby fabricate a three-dimensional microstructure having a shape corresponding substantially to the designed three-dimensional shape.
