Abstract
A method of forming a master mold (), comprising: a) forming a plurality of microstructure portions () in a substrate formed of a first material by a first micromachining process, each microstructure portion comprising a shaft () and a distal tip (); b) preparing a negative mold () of the plurality of microstructure portions, wherein the mold is formed of a second material and comprises a plurality of cavities () corresponding to each microstructure portion in the plurality of microstructure portions (); c) electroplating a metal () onto the negative mold to fill each cavity in the plurality of cavities and to form a base layer () extending from the negative mold; d) forming a proximal section () for each of the microstructures in the base layer using a second micromachining process (e.g. mechanical micromachining); and e) before or after said step d), removing the negative mold from the metal to form a master mold.
