Abstract:
A method of fabricating an array of microstructures comprising the steps of:preparing a substrate with an electrically-conductive portion; forming an insulating mask layer on the electrically-conductive portion; forming a plurality of openings in the insulating mask layer to expose the electrically-conductive portion; electroplating a first plated layer or electrodepositing an electrodeposited layer in the plurality of openings and extending isotropically onto an adjacent portion of the insulating mask layer to form a semispherical or semicylindrical layer; and forming a second plated layer on the first plated layer or electrodeposited layer and on the electrically-conductive portion by electroless plating to thereby form a microstructure array comprising semispherical or semicylindrical microstructures.
