Hybrid method for forming microstructural array forming die, method for producing microstructural array, and use method

摘要

A method of forming a master mold (52).A)Forming a plurality of microstructured portions (42) within the substrate formed from the first material;B) preparing a negative molding die (46) of said plurality of microstructured portions;C) the metal (50) is electroplated onto the negative molding die to fill the cavities in the plurality of cavities and form a base layer (54) extending from the negative moldD) the second micromachining processUsing mechanical micro machiningForming a proximal section (56) for each of the microstructures in said base layer;E) the negative molding die is removed from the metal before or after the step d to form a master mold.
