ABSTRACT:
A method for assembly including the steps of:(a) providing a plurality of microstructure components with each of the components having a bottom with the same three dimensional shape;(b) forming a mold with at least one protuberance from a surface thereof so that the at least one protuberance has the same shape;(c) molding a moldable substrate with the mold to form a molded substrate having a surface with at least one recess having the same shape; and(d) positioning a first of the plurality of microstructure components into said at least one recess. Each of the microstructure components may be formed by a masking and etching process, with the mold being formed by the same masking and etching process. The positioning step may consist of mixing the microstructure components with a fluid to form a slurry; and depositing the slurry on the surface of the molded substrate to cause the first of the plurality of microstructure components to self-align in the recess.
