This paper presents a fabrication method of various nickel stamps based on anodic aluminum oxide (AAO) and nickel electroforming (NE) processes. By AAO process, master templates which have closely-packed nano dimple or pore structure array are fabricated. Then nickel stamps having negative surface topology of the master templates are fabricated by NE process. Also positive nickel stamps are fabricated from the negative stamps by NE process with the help of nickel passivation technique. So achieved nickel stamps are employed in injection molding and hot embossing processes for replication of nano-structured surfaces.
